Problems solved by technology
It can be seen that the existing methods cannot solve the current practical problems, and the existing calculation methods have the following deficiencies: 1. When calculating the total amount of available water resources in oases and non-vegetation water consumption, due to the outdated calculation methods, the The calculation results are too rough, resulting in large discrepancies in the final calculation of the suitable scale of the oasis, which affects the misjudgment of policies and planning; 2. Due to changes in the development of the times and the pursuit of goals, most of the calculation models have not been changed accordingly, and it has not been possible to further integrate The newly generated water consumption unit is taken into account, resulting in large deviations in the calculation results

Embodiment 1
[0040] In order to make the invention easy to understand, the Manas River Basin, where the ecological problems of oases are becoming more and more prominent, is taken as an example to illustrate the invention, and the detailed steps are as follows.
[0041] 1) Determination of the scale of the current oasis
[0042] The eCognition remote sensing classification software was used to extract the relevant ground feature information of the Manas River Basin. According to the actual situation of land use in the Manas River Basin, combined with the mechanism of oasis occurrence, the research of Chinese scholars on artificial oasis and natural oasis, and the second-level classification standard of my country's land resource classification system, the artificial oasis and natural oasis are divided. Therefore, the artificial oasis in the Manas River Basin is divided into five types of land, including forest land, grassland, cultivated land, water area and building land, among which the ...

The invention discloses a method for calculating the suitable scale and stability of an oasis in an inland river basin, which is characterized by mainly comprising the following steps of 1) determining the scale of the present oasis; 2) dividing abundant and dry water resources; 3) constructing the suitable scale model of the oasis in the inland river basin; 4) carrying out the stability assessment of oasis in inland river basin. In accordance with that prior art, the outstanding advantages of the invention are that by constructing the calculation formula of the suitable scale of the oasis, and combining with the current satellite remote sensing technology, the long-term drought in the inland river basin has been solved, the problems that the suitable area and stability of oasis in semi-arid area can not be determined accurately is solved, and technical support is provided for the stable development of the oasis safety, and the method has stronger practical value for the control and planning of the oasis area. Meanwhile, the method is simple in calculation and reasonable in result, plays an important role in the oasis management and social and economic benefits in arid and semi-arid areas of inland river basin, and can be used in practical projects.
Description
technical field [0001] The invention relates to a method for calculating the suitable scale and stability of oases in inland river basins, in particular to a method for calculating the suitable scale and stability evaluation of oases in arid and semi-arid areas in inland river basins based on ArcGIS, which belongs to scale control field. Background technique [0002] Oasis is the product of the combination of man and nature, the foundation of human existence, and the foundation for the development and construction of inland river basins. With the rapid development of population and economy in inland river basins, the expansion of oasis area has become the main driving force for regional development and construction. The expansion of the oasis area has increased the demand for water resources in the region, resulting in the over-exploitation of surface water and groundwater in some areas. Coupled with the unlimited expansion of the oasis agricultural land, the originally lim...
