【摘要】：[目的]面对人地关系紧张、粮食安全严峻的形势,走集约挖潜、生态兼顾的耕地利用模式是可持续发展之路的必然选择。因此,如何协调好耕地集约利用与耕地生态安全之间的关系,成为亟待解决的关键性问题。[方法]文章运用协调发展理论,构建耕地集约利用与耕地生态安全协调发展评价模型,分析西安市1999~2014年间的耕地集约利用与耕地生态安全协调发展程度的时空分异。[结果]研究表明:从时间上看,协调发展度整体上逐年增加,协调发展等级由最初的轻度失调转为良好协调发展型,但近年来协调发展度呈现缓慢下降趋势;从空间上看,西安市协调度与协调发展度都存在着显著的地区差异,其中高陵县、灞桥区的变化较显著。[结论]研究结果可为西安市耕地集约利用与耕地生态安全协调发展,实现耕地生态集约化提供科学依据。
[Abstract]:[objective] in the face of the tense relationship between man and land and the severe situation of food security, it is the inevitable choice of sustainable development to take the mode of cultivated land utilization with intensive exploitation and ecological consideration. Therefore, how to coordinate the relationship between intensive utilization of cultivated land and ecological security of cultivated land has become a key problem to be solved. [methods] based on the theory of coordinated development, the evaluation model of intensive utilization of cultivated land and ecological security of cultivated land was established, and the temporal and spatial differentiation of the degree of coordinated development between intensive utilization of cultivated land and ecological security of cultivated land was analyzed in Xi'an City from 1999 to 2014. [results] the results show that, in terms of time, the degree of coordinated development has increased year by year, and the level of coordinated development has changed from the initial slight imbalance to a good one, but in recent years the degree of coordinated development has shown a slow downward trend; from a spatial point of view, There are significant regional differences in the degree of coordination and development in Xi'an, among which the changes in Gaoling County and Baqiao District are significant. [conclusion] the results can provide scientific basis for the coordinated development of intensive utilization of cultivated land and ecological security of cultivated land and the realization of ecological intensification of cultivated land in Xi'an.
