Abstract:

【Objective】The aim of this work is to conduct a quantitative analysis of the endowment pattern of water resources in the middle Yangtze River basin and its spatial relationship with natural protected areas. This would provide a scientific basis for the rational planning and layout of basin-type natural protected areas. 【Method】By constructing a comprehensive evaluation model of water resource endowments and combining ArcGIS technology, the relationship between water resource endowment patterns and different types of natural protected areas in the middle Yangtze River basin was quantitatively revealed from the perspective of quantity and density. 【Result】The higher, high, medium, low and no endowment areas in the middle Yangtze River basin accounted for 2.61%, 29.13%, 40.01%, 18.58% and 9.67% of the study area, respectively. The high endowment area was located in Poyang Lake, and the no endowment area was located in the Tangbai River basin. Except for geoparks, other natural protected areas had a high coupling relationship with water resource endowments, and there were obvious differences in the correlations between different types of water resources and their ecosystem functions and social and economic values.South Poyang Lake and the Liangzi Lake Group, which had a high endowment of water resources, had very few natural protected areas in the fourth-level basin, and the protection and development control of water resources in this area should be strengthened. 【Conclusion】A comprehensive evaluation model of water resource endowments with nature conservation as the goal, combined with ArcGIS technology, can quantitatively reveal the pattern of water resource endowments and quickly identify its conservation vacancy status, which is conducive to the construction of water resources protection and basin-type nature reserve systems in China.
