Evaluation and Optimization of Land Ecological Security
摘要
Abstract
Maintaining land ecological security is conducive to ensuring the sustainable use of land resources.Taking Hefei as an example,with the PSR model,this paper selects 19 indicators from three dimensions of pressure,state and response to construct the evaluation index system of land ecological security,and then evaluates the land ecological security index of Hefei from 2011 to 2020.The land ecological security pressure index and state index in Hefei show a small changing range within the 10 years,with the land ecological security response index from 0.0819 to 0.3091,and an increase by 50.81％for the land ecological security comprehensive index from 2011 to 2020.The countermeasures on the land ecological security in Hefei include improving land laws and regulations to strengthen land administration measures,adhering the concept of green land development to plan scientifically and rationally the land use,strengthening relevant publicity efforts to improve the people's awareness of ecological protection.关键词
