基于熵权物元模型的福建山区耕地生态安全评价——以清流县为例
Ecological Security of Cultivated Land in Qingliu County Analyzed by Entropy Matter-Element Model
摘要
Abstract
Taking Qingliu county,a typical mountainous agricultural region in Fujian,as an example,this study selected 16 indicators,such as per capita cultivated land,to analyze the ecological security of the area.From 2010 to 2016,data were collected to fit in the entropy-based matter-element model for comparisons and evaluations.The results showed that (1) the security level of the area cultivated land belonged to the " transition toward security" classification,but the trend could possibly reverse;(2) programs like the " Comprehensive Utilization of Industrial Solid Wastes" enhanced the eco-security,but the population growth as well as 5 other factors could restrict the extent of potential improvement;and,(3) in general,the conclusion drawn by this study agreed with that obtained by the multi-index comprehensive evaluation with a few year-to-year discrepancies;however,the matter-element model was deemed more intuitive and accurate in analyzing the impact of individual indicators.关键词
