Description

Technical Field

[0001] The present invention relates to the fields of ecological restoration and environmental investigation, and particularly relates to a method for identifying key areas for ecological protection and restoration based on ecosystem services. Background Art

[0002] With the increasing attention of people to the ecological environment, more and more people begin to focus on the restoration of ecosystems. However, in the process of ecosystem restoration, it is impossible for the restoration plans corresponding to all places to be the same, and it is necessary to carry out restoration according to the actual situation. In this process, the identification of key areas for regional ecological protection and restoration is particularly important. The identification of this key area reflects the differences in the ecosystem service functions of the region and is an important basis for regional land use development guidance and ecological space control.

[0003] When identifying existing ecological key areas, it is usually to identify large-scale ecological belts or regional groups, without studying small-scale communities or village boundaries. At the same time, the ecosystem service value and the identification of key areas are not well combined. Usually, it is the superposition of ecological problems, and the final result is even less scientific. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for identifying key areas for ecological protection and restoration based on ecosystem services, which can fully connect the ecosystem service value with the identification of key areas for ecological restoration, making the identification of corresponding key areas for ecological restoration more scientific.

[0005] The basic solution provided by the present invention: A method for identifying key areas for ecological protection and restoration based on ecosystem services, comprising the following steps:

[0006] S1. After determining the corresponding research area, according to the existing land data corresponding to the area to be studied, based on the existing village boundaries of the research area, and according to the corresponding land use types, divide the corresponding area to be studied; the existing land data includes land use change survey data;

[0007] S2. Establish a model, taking the village boundary as a unit, evaluate the ecological value and economic value of the ecosystem services of each village boundary within each land use type, obtain the corresponding ecological value evaluation value and economic value evaluation value, and add the ecological value evaluation value and economic value evaluation value to obtain the comprehensive value corresponding to each land use type;

[0008] S3. According to the corresponding comprehensive value and the corresponding principle of proximity, use the natural break method to divide the corresponding comprehensive value into 5 levels, divide the two levels with the highest value into the core protection category, the lowest value into the ecological restoration category, and the middle two levels into the ecological coordination category;

[0009] S4. Based on the relevant ecological environment information of the three major categories of corresponding regions, identify the regions with serious ecological environment problems in the above three categories, and respectively obtain the corresponding key protection areas, key ecological restoration areas, and key ecological coordination areas;

[0010] S5. Identify the ecological problems and ecological functions of each key area, and then formulate their respective ecological protection plans.

[0011] The principle and advantages of the present invention are as follows: First, the area to be studied is determined, and then the corresponding existing land data is collected, including the land use change survey data. Then, taking the existing village boundaries as units, the area to be studied is divided according to the corresponding land use types. After that, by evaluating the ecological value and economic value of each village boundary within each land use type, the comprehensive value corresponding to each land use type can be obtained. Then, grading is carried out according to the corresponding comprehensive value, so that the village boundaries corresponding to each land use type can be comprehensively evaluated, making the obtained results more comprehensive and scientific. Then, these comprehensive values are graded according to the natural break method to obtain the core protection category, ecological restoration category, and ecological coordination category. In this way, the areas for ecological environment verification for each category can be identified in turn, and the corresponding key areas in each category can be obtained, so that the respective key areas can be scientifically processed, more accurate and scientific.

[0012] In this application, first, the economic value and ecological value are evaluated. Through the setting of two criteria, the identification of the key ecological restoration areas for the corresponding comprehensive evaluation is connected with the corresponding ecosystem service value, so that the finally identified key ecological restoration areas are more scientific and accurate.

[0013] At the same time, when classifying and identifying the categories of comprehensive values, not only the corresponding comprehensive values themselves are considered, but also the corresponding proximity principle is followed. In this way, the classification of the categories of comprehensive values can be more concentrated, and it will not lead to the dispersion of areas in the same category, which will greatly increase the cost required for corresponding protection. At the same time, the proximity principle can also make the identification of subsequent key areas more convenient and fast.

[0014] At the same time, when conducting value evaluation, it is based on village boundaries as units, so the corresponding evaluation scale is smaller, the corresponding accuracy is higher, and it is also more comprehensive.

[0015] Furthermore, the ecological value includes climate regulation (including gas regulation), water conservation, soil formation and protection, waste treatment, and biodiversity protection; the economic value includes food production and raw material supply.

[0016] The more types involved in ecological value and economic value, the more accurate and scientific the final evaluation result will be, which can greatly improve the final accuracy.

[0017] Further, the S4 includes:

[0018] S41. Obtain relevant ecological environment information of three major categories of corresponding regions;

[0019] S42. According to the category to be judged, match the relevant ecological environment information corresponding to this category, identify the regions with serious ecological environment problems, and obtain the corresponding key regions. The key regions include core protection key regions, ecological restoration key regions, and ecological coordination key regions.

[0020] Further, the S42 also includes reclassifying the corresponding key regions according to the actual regional restoration needs and key treatment elements.

[0021] Through the form of reclassification, the corresponding key regions can be implemented to the corresponding village boundaries, so that the identification of the corresponding key regions will be more accurate.

[0022] Further, the S5 includes:

[0023] Identify the ecological problems and ecological functions corresponding to different types of key regions to obtain the corresponding ecological information;

[0024] According to the corresponding ecological information, determine the main direction of protection and formulate the corresponding ecological protection plan.

[0025] Through the formulation of the ecological protection plan, it is possible to better, more scientifically, and more precisely manage and protect each region.

[0026] Further, the land use types include cultivated land, garden land, forest land, grassland, water area, and others.

[0027] Through the diverse classification of land use types, it is possible to more intuitively view the respective values corresponding to each land use type. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, the land use types include cultivated land, orchard land, forest land, grassland, water area and others.

[0034] S2. Establish a model, taking the village boundary as a unit, evaluate the ecological value and economic value of the ecosystem services within each land use type for each village boundary, obtain the corresponding ecological value evaluation value and economic value evaluation value, and add the ecological value evaluation value and economic value evaluation value to obtain the comprehensive value corresponding to each land use type. In this embodiment, the ecological value includes climate regulation (including gas regulation), water conservation, soil formation and protection, waste treatment, and biodiversity protection; the economic value includes food production and raw material supply.

[0035] S3. According to the corresponding comprehensive value and the corresponding principle of proximity, use the natural break method to divide the corresponding comprehensive value into 5 levels, classify the first and second levels with the highest value as the core protection category, the lowest value as the ecological restoration category, and the middle two levels as the ecological coordination category. In this embodiment, taking Wansheng Economic Development Zone as an example, evaluate the comprehensive value of ecosystem services for each village boundary in Wansheng Economic Development Zone, and obtain as shown in Figure 2 : Obtain the corresponding distribution map of the comprehensive value of the ecosystem service system in Wansheng Economic Development Zone. In this process, the corresponding comprehensive value is divided into 5 levels with corresponding different colors.

[0036] In this embodiment, if there is a village boundary corresponding to the ecological coordination category within the area of the core protection category during the division of the comprehensive value, then when dividing, the category of this village boundary will be classified as the core protection category.

[0037] S4. According to the relevant ecological environment information of the three corresponding categories of areas, identify the areas with serious ecological environment problems in the above three categories, and respectively obtain the corresponding key areas for core protection, key areas for ecological restoration, and key areas for ecological coordination.

[0038] The said S4 includes:

[0039] S41. Obtain relevant ecological environment information for corresponding regions in three major categories;

[0040] S42. According to the category to be judged, match the relevant ecological environment information corresponding to this category, identify the regions with serious ecological environment problems, and obtain the corresponding key regions. The key regions include core protection key regions, ecological restoration key regions, and ecological coordination key regions. According to the actual regional restoration needs and key governance elements, reclassify each corresponding key region.

[0041] In this embodiment, after comprehensively evaluating the Wansheng Economic Development Zone, five levels are obtained, and then they are classified into corresponding types. Then, identify the core protection key regions for the regions of the core protection category, identify the ecological restoration key protection regions for the regions of the ecological restoration category, and identify the ecological restoration key protection regions for the regions of the ecological coordination category, to obtain the identification map of the ecological restoration key regions of the Wansheng Economic Development Zone as shown in Figure 3 In this embodiment, the core protection key regions include Beimen Village, Nanmen Village, Baihua Village, Caiyuan Village, and Bailonghu Village; the ecological restoration key regions include Wentang Village, Qilin Village, Jianshe Village, Yingzhai Village, Minquan Village, Wangjiaba Village, Shiqiao Village, Nantong Village, the urban area of Wansheng District in Wandong Town, and Bangshang Village; the ecological coordination key regions include Pingba Village, Xinglong Village, Liangfeng Village, and Tianba Village. At the same time, in this embodiment, there are also key regions for agricultural development, including Xinghe Village, Matouqiao Village, and Xinmu Village. By identifying the key regions for agricultural development, the development of agriculture can also be better constructed.

[0042] S5. Identify the ecological problems and ecological functions of each key region, and then formulate their respective ecological protection plans.

[0043] The S5 includes:

[0044] Identify the ecological problems and ecological functions corresponding to different types of key regions to obtain corresponding ecological information;

[0045] According to the corresponding ecological information, determine the main attack directions for corresponding protection, and formulate corresponding ecological protection plans.

[0046] In this embodiment, the main attack directions of each key region are as follows: for the core protection key region, the ecological function value of this region is relatively high and it relies on a good mountain and water ecological protection barrier, becoming the core area for protecting ecological resources. With the primary goals of soil and water conservation, water conservation, and natural ecological conservation, overall consideration is given to the integrity, coordination, safety, and functionality of ecological resources. Orderly carry out ecological relocation within nature reserves and protect the biodiversity of mountain wild animals and plants; improve the quality and quantity of forest ecological systems and optimize the forest stand structure; build biodiversity protection corridors and protect biological stepping stones.

[0047] Key areas for ecological collaboration. In these areas, ecological resources are average, but ecological problems are prominent. Ecological restoration mainly focuses on auxiliary restoration. While carrying out ecological restoration, high-quality green public open spaces should be created to enhance the natural characteristics of human living spaces, strengthen the connectivity of urban green public ecological spaces and the simultaneous through-connection of urban and rural green spaces, and form a complete green ecological space.

[0048] Key areas for ecological restoration. These areas are concentrated distribution areas of construction land with a lack of ecological resources, and mainly focus on creating elastic urban spaces. Green isolation belts, greenways, green corridors, etc. should be built in combination with urban roads, mountains, water systems, wetlands, and forests to construct urban cluster isolation belts and optimize the landscape pattern of mountains and waters; urban protection green belts should be built to play the functions of ecological corridor transition, isolation, and connectivity.
