Abstract
Description
Technical Field
[0001] The present invention relates to the field of water resource management, and in particular to a water resource adaptive management and water volume accounting system taking into account climate change. Background Art
[0002] "Mountainous area - artificial oasis - desert oasis" is a typical natural water cycle process in arid inland river basins. Mountainous areas are runoff formation areas, plains are runoff dissipation areas, and deserts and desert areas are river dissipation areas. The strong human influence of oasis water cycle and the natural exhaustion of desert water cycle are a one-way process with sensitive response from top to bottom. Excessive increase in water use in the upper and middle reaches will inevitably lead to a decrease in water volume in the lower reaches and deterioration of the desert ecological environment.
[0003] In order to cope with water security issues under global changes, humans have increased the amount of available water resources as much as possible through engineering measures such as artificial rainfall, dam building, and water diversion. At the same time, they have also further explored the potential for the utilization efficiency of traditional water resources and developed and utilized unconventional water resources through a series of measures such as runoff potential, water-saving irrigation, and optimized allocation. Summary of the invention
[0004] To solve the above problems, the present invention provides a water resources adaptive management and water volume accounting system that takes climate change into consideration, which is used to coordinate the balance and game of water resources between natural oases and artificial oases in wet and dry years.
[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: A water resources adaptive management and water quantity accounting system considering climate change, comprising:
[0006] Greening based on water module: predict the ecological water demand of natural oases through the phreatic evaporation method, area quota method and Averyanov formula method, collect and analyze the formation and consumption patterns of water resources in inland rivers, determine the water consumption and water resource carrying capacity of artificial oases based on the difference between the ecological water demand of natural oases and the water resources of inland rivers, and build artificial oases;
[0007] Scheduling module: Based on the changes in water resources, when there are consecutive wet years, both economic and social water use and ecological environment water use will increase. When there are consecutive dry years, economic and social water use will decrease and priority will be given to ecological environment water use. The amount of irrigation for artificial oases will be dynamically reduced according to the amount of water resources in dry years to reduce the water consumption of artificial oases. A cross-year joint allocation of groundwater, plain reservoirs and mountain reservoirs will be established to transfer water from large and shallow plain reservoirs to deep mountain reservoirs.
[0008] The above scheme has the following beneficial effects:
[0009] 1. In this plan, the ecological water demand of natural oases is predicted based on the phreatic evaporation method, the area quota method and the Aviryanov formula method, and the water resource formation and consumption patterns of the inland rivers in the region are counted, the oasis carrying capacity in the region is calculated, and artificial oases are established to supplement the oasis area in order to efficiently utilize water resources and improve the ecological environment.
[0010] 2. In this plan, since the amount of water resources is affected by the climate, there will be wet years and dry years. In wet years, the amount of water resources increases, and each field that needs water resources can increase the proportion of water resources. In dry years, due to the reduction of water resources, conflicts will arise in various fields that need water resources. When there are consecutive dry years, priority will be given to reducing economic and social water use, reducing the conversion of water resources into economic resources, ensuring water use for the ecological environment, and reducing the ecological chain reaction caused by the reduction of water resources in the arid inland areas. Secondly, reduce the amount of irrigation for artificial oases. Artificial oases are based on artificial water systems for water supply, which can facilitate the control of water resource increases and decreases. At the same time, as an enhancement of the existing environment, the role of artificial oases in reducing the impact on the ecology is less than the impact caused by changes in natural oases.
[0011] 3. In this plan, due to the poor water retention capacity of the soil in the arid inland, the natural rainfall infiltration is serious, and the groundwater resources are abundant, so the groundwater allocation is a very important part of water resource management. Establish a cross-year joint allocation of water resources. When water resources are scarce in dry years, the water volume of plain reservoirs will be transferred to deep mountain reservoirs to reduce the evaporation area of the reservoirs, thereby reducing the loss of water resources.
[0012] Furthermore, the area and distribution of artificial oases in the water-greening module are designed based on the principle of water balance in the watershed.
[0013] Beneficial effects: Artificial oases need to consume water resources in natural river basins, which will inevitably lead to a reduction in water resources downstream. Design based on the principle of water balance in river basins can ensure that the distribution area of artificial oases is large and the water resource utilization efficiency is high.
[0014] Furthermore, each artificial oasis is equipped with a water network for drawing out water resources from the artificial oasis.
[0015] Beneficial effects: Conventional artificial oases only introduce water resources for consumption, and it is difficult to recycle water resources when reducing the area of artificial oases. The water network can recycle the excess water resources of artificial oases when reducing the irrigation of artificial oases, and at the same time can build a water cycle between artificial oases and natural waters, reducing the accumulation of salt caused by the continuous introduction of water resources into artificial oases.
[0016] Furthermore, it also includes a medium- and long-term water resources forecasting model. The medium- and long-term water resources forecasting model is based on the analysis of the evolution of temperature, glaciers, and runoff. It predicts the distribution and water levels of rivers, lakes, reservoirs, and groundwater, and flexibly allocates water resources in different regions based on the forecast results.
[0017] Beneficial effects: The forecast model can predict the changes in the total amount of water resources in advance, so that water resources can be allocated in advance to cope with the water resource situation. Since the amount of water resources in different regions is different, water resources can be flexibly allocated after obtaining the forecast results.
[0018] Furthermore, the scheduling module is also used to couple with the water consumption of oasis users in the event of changes in water resources, and to optimize the allocation of water resources in different regions, different water sources, and different users in combination with the medium- and long-term water resources forecasting model.
[0019] Beneficial effects: In addition to the ecological environment consuming water resources, oasis residents, or users, also consume water. By coupling the water consumption of oasis users with the changes in water resources, a more realistic oasis water consumption can be obtained.
[0020] Furthermore, the scheduling module also includes the construction of artificial underground reservoirs, which are used for the joint allocation of groundwater, plain reservoirs and mountain reservoirs, and are used to reduce the natural evaporation of stored water.
[0021] Beneficial effects: Artificial underground reservoirs have lower natural evaporation than mountain reservoirs, but are more expensive. They can reduce water loss in dry years and are convenient for allocation with groundwater, which can easily regulate groundwater levels.
[0022] Furthermore, the medium- and long-term water resources forecasting model is also used to establish a cross-year groundwater resource optimization allocation model with long-series runoff data as model input, and output an optimal allocation plan for groundwater and artificial groundwater reservoir resources that reduces water in abundant seasons and increases water in scarce seasons.
[0023] Beneficial effects: Natural oases rely on rivers and shallow groundwater. In dry years, the groundwater level decreases, which has a great impact on natural oases that rely on groundwater. Therefore, the groundwater level needs to be maintained in dry years to reduce the impact on natural oases that rely on groundwater. At the same time, increasing the proportion of groundwater in dry years can reduce water loss caused by evaporation, thereby conserving more water resources.
[0024] Furthermore, artificial groundwater reservoirs are located within natural oasis ecosystems or mountains.
[0025] Beneficial effects: Natural oases usually have higher soil water retention, which can be used to reduce the cost of water infiltration and enhance the ecological stability of natural oases. Mountains are more easily replenished by natural precipitation, and water bodies have a certain gravitational potential energy, which can be easily allocated.
[0026] Furthermore, the scheduling module is also used to investigate the number of naturally germinated plant types and the number of migrating animal species in each area of the artificial oasis. When the irrigation volume of the artificial oasis is dynamically reduced according to the water resources in the dry year, priority is given to reducing the number of germinated plant types and the number of migrating animal species in the areas with a small number.
[0027] Beneficial effect: The amount of irrigation for artificial oases is reduced preferentially in areas with less ecological impact. By collecting the number of naturally germinated plant types and the number of migrating animal species, the importance of the artificial oasis in the ecology can be determined, and the areas with reduced irrigation can be planned.
[0028] Furthermore, the species and numbers of migrating animals were collected using infrared cameras in the wild.
[0029] Beneficial effects: Infrared cameras in the wild can monitor for a long time and have good image acquisition performance both during the day and at night, making it easy to monitor wild animals and count their species and numbers.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] The following is further described in detail through specific implementation methods:
[0037] As attached Figure 1-Figure 2 Shown: A water resources adaptive management and water quantity accounting system considering climate change, including:
[0038] Greening based on water module: predict the ecological water demand of natural oases through the phreatic evaporation method, area quota method and Aviryanov formula method, collect and analyze the water resource formation and consumption patterns of inland rivers, and determine the water consumption, water resource carrying capacity, distribution and area of artificial oases based on the difference between the ecological water demand of natural oases and the water resources of inland rivers and the principle of water balance in the river basin, and then build artificial oases;
[0039] Scheduling module: Based on the changes in water resources, when there are consecutive wet years, both economic and social water use and ecological environment water use will increase. When there are consecutive dry years, economic and social water use will decrease and priority will be given to ecological environment water use. The amount of irrigation for artificial oases will be dynamically reduced according to the amount of water resources in dry years to reduce the water consumption of artificial oases. A cross-year joint allocation of groundwater, plain reservoirs and mountain reservoirs will be established to transfer water from large and shallow plain reservoirs to deep mountain reservoirs.
[0040] The specific implementation process is as follows: First, based on the groundwater evaporation method, the area quota method and the Aviryanov formula method, the ecological water consumption demand of the natural oasis is predicted, and the water resource formation and consumption patterns of the inland rivers in the region are counted, the oasis carrying capacity in the region is calculated, and artificial oases are established to supplement the oasis area in order to efficiently utilize water resources to improve the ecological environment, expand the desert greening area, and slow down or inhibit desertification.
[0041] Since the amount of water resources is affected by the climate, there will be wet years and dry years. In wet years, the amount of water resources increases, and each field that needs water resources can increase the proportion of water resources. In dry years, due to the reduction of water resources, conflicts will arise in various fields that need water resources. When there are consecutive dry years, priority should be given to reducing economic and social water use, reducing the conversion of water resources into economic resources, ensuring water use for the ecological environment, and reducing the ecological chain reaction caused by the reduction of water resources in the arid inland areas. Secondly, reduce the amount of irrigation for artificial oases. Artificial oases are based on artificial water systems for water supply, which can facilitate the control of water resource increases and decreases. At the same time, as an enhancement of the existing environment, the role of artificial oases in reducing the impact on the ecology is less than the impact caused by changes in natural oases.
[0042] In arid inland areas, due to poor soil water retention capacity and serious natural rainfall infiltration, groundwater resources are abundant, so groundwater allocation plays a very important role in water resource management. Establish a cross-year joint water resource allocation system. When water resources are scarce in dry years, water from plain reservoirs can be transferred to deep mountain reservoirs to reduce the evaporation area of the reservoirs, thereby reducing water resource loss.
[0043] Artificial oases are all equipped with water networks for drawing out water resources from the artificial oases.
[0044] In artificial oases, following the principle that salt comes with water and goes with water, maintaining the desalination or non-salt accumulation of artificial oasis soil, and the reasonable discharge of harmful substances (such as salt) in the basin are the key to regulating the water cycle of the oasis. The water network can build a water network from the artificial oasis to the natural basin, which can not only build a water cycle, but also reduce the probability of excessive salt accumulation in the artificial oasis. At the same time, the water network can conveniently implement water resource regulation, and recycle the excess water resources of the artificial oasis when reducing the irrigation of the artificial oasis.
[0045] It also includes a medium- and long-term water resources forecasting model. The medium- and long-term water resources forecasting model is based on the analysis of the evolution of temperature, glaciers, and runoff. It predicts the distribution and water levels of rivers, lakes, reservoirs, and groundwater, and makes flexible allocation of water resources to different regions based on the forecast results.
[0046] The prediction model can predict the changes in the total amount of water resources in advance, so that water resources can be allocated in advance to cope with the water resource situation. Since the amount of water resources in different regions is different, water resources can be flexibly allocated after obtaining the prediction results.
[0047] The scheduling module is also used to couple with the water consumption of oasis users in response to changes in water resources, and to optimize water resource allocation in different regions, different water sources, and different users in combination with the medium- and long-term water resources forecasting model.
[0048] In addition to the ecological environment consuming water resources, oasis residents, or users, also consume water. Coupling the water consumption of oasis users with changes in water resources can derive a more realistic oasis water consumption.
[0049] The scheduling module also includes the construction of artificial underground reservoirs, which are used for the joint allocation of groundwater, plain reservoirs and mountain reservoirs. Artificial underground reservoirs are used to reduce the natural evaporation of stored water. Artificial underground reservoirs are located in natural oasis ecology or mountains.
[0050] Artificial underground reservoirs have lower natural evaporation than mountain reservoirs, but are more expensive. They can reduce water loss in dry years and are convenient for connecting with groundwater for allocation. They can easily regulate groundwater levels to maintain the natural oasis ecology that relies on groundwater resources in dry years. Natural oases usually have higher soil water retention, which can reduce water infiltration rate and enhance the ecological stability of natural oases. Mountains are easier to replenish through natural precipitation, and reservoir water has a certain gravitational potential energy, which can be easily allocated.
[0051] The medium- and long-term water resources prediction model is also used to establish a cross-year groundwater resource optimization allocation model with long-series runoff data as model input, and output an optimal allocation plan for groundwater and artificial groundwater reservoir resources that reduces water in abundant seasons and increases water in scarce seasons.
[0052] The scheduling module is also used to investigate the number of naturally sprouted plant types and the number of migrating animal species in each area of the artificial oasis. The species and number of migrating animals are collected through field infrared cameras. When the irrigation volume of the artificial oasis is dynamically reduced according to the water resources in the dry year, the number of sprouted plant types and the number of migrating animal species are reduced first.
[0053] The amount of irrigation for artificial oases should be reduced in areas with less ecological impact. By collecting the number of naturally germinated plant types and the number of migrating animal species, the importance of the artificial oasis in the ecology can be judged, and the area where irrigation is reduced can be planned. Field infrared cameras can monitor for a long time and have good image acquisition performance both during the day and at night, making it easy to monitor wild animals and count their species and numbers.
[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
