摘要
在丝绸之路经济带建设背景下,运用PSR模型构建西北五省森林生态安全评价指标体系,通过熵权法计算2013年至2017年西北五省的森林生态安全指数,并比较分析了2013年至2017年西北五省森林生态安全变化情况。结果表明:西北地区森林生态安全水平由高到低依次为陕西、甘肃、新疆、宁夏、青海;其中陕西和甘肃处于较安全等级,其余三省处于不安全等级,总体相差较大。根据实证分析结论提出了相关发展建议。
The paper used PSR model to construct the evaluation index system of forest ecological security in five northwestern provinces and calculated the forest ecological security index of five northwestern provinces from 2013 to 2017 by the entropy method, under the background of the construction of the Silk Road Economic Belt. It also compared the changes of forest ecological security in five northwestern provinces from 2013 to 2017. The results showed that the level of forest ecological security in the northwest is from Shaanxi to Gansu, Xinjiang, Ningxia and Qinghai. Among them, Shaanxi and Gansu are in the relatively safe level, and the other three provinces are in the unsafe level, the overall difference is large. Finally, it put forward the relevant development suggestions according to the empirical analysis conclusions.
