Research on the Identification of the Synergistic Relationship Between Agricultural Water Saving and Ecological Security of Hetao Irrigation Area
摘要
Abstract
Clarifying the game synergy relationships between agricultural water saving and ecological security is the foundation for determining the water-saving potential as well as maintaining ecological security in irrigation areas.This study adopted ecological value calculation,tend-ency analysis and formulated ecological security area approaches to identify the matching degree between the supply and demand of ecological values.On this basis,the study analyzed the matching situation of ecological value supply and demand in the Hetao irrigation area,the evolu-tion laws of the scale of agricultural irrigation,the area of forests,grasslands and lakes and ecological value under the scenario of agricultural water conservation,clarified the groundwater burial depth threshold for maintaining the ecological functions of forests,grasslands,lakes and farmlands,and identified the game synergy relationship between agricultural water conservation and ecological security.The results show that the supply of ecological values relies on human activities such as ecological water replenishment and surface irrigation,and there is a certain degree of mismatch with ecological demand.With the advancement of agricultural water saving,groundwater depth increases,the ecological security area decreases,and ecological functions weaken.There exists a competitive relationship between agriculture and ecology in terms of water and land use.A reasonable ecological groundwater depth is a prerequisite for maintaining the ecological functions of irrigation areas.关键词
