基于InVEST模型的甘肃省水安全格局分析
Analysis of Water Security Pattern in Gansu Province Based on the InVEST Model
摘要
Abstract
Clarifying water security patterns plays an important role in the sustainable management of water resources and the protection of ec-ological environment.Based on the five periods of land use data from 2000 to 2020,the spatial and temporal characteristics of water supply,water demand and water resources risk zones in Gansu Province were explored by using the InVEST model,the supply and demand index method and the spatial correlation model,and the spatial correlation analyses of water resources risk zones were carried out by means of the global Moran's index and the local Moran's index.The results show that during the 21 years,the spatial distribution pattern of water produc-tion in Gansu Province shows high in the southeast and low in the northwest,and the water production shows a good trend of increasing year by year;the high value areas of water demand are mainly concentrated in the urban built-up areas and the agricultural concentration zones in the Hexi oasis,and the water demand is relatively balanced in different periods;the high-risk areas of water resources are mainly located in Hexi Corridor area,and the low-risk areas are located in the east Longnan area and near the northern foot of Qilian Mountains;the water re-sources risk areas,water demand and water production all show strong spatial correlation in their spatial distribution.关键词
