摘要
文中从狭义和广义对林业生态安全概念进行界定,分析不同定义下生态安全问题的表现;从林业生态安全评价和预测、预警、阈值方面对既有研究进行梳理,比较指标体系构建、指标权重计算、综合评价和结果应用过程中所采用的模型和方法;针对林业生态安全研究存在的不足提出展望:1)引入大数据方法与技术;2)加强林业生态安全阈值、预测与预警研究;3)加强政策体系研究。
The paper defines the concept of forestry eco-security in both narrow sense and broad sense to analyze the manifestation of eco-security under the different definitions.Then the previous studies on the evaluation,prediction,early warning and threshold of forestry eco-security are reviewed,and the models and methods used in the process of index system development,weight calculation,comprehensive evaluation and results application are also summarized and compared.With the eye on some deficiencies in the studies on forestry eco-security,the future research is prospected:1)The big data methods and technologies should be introduced;2)The threshold,prediction,and early warning of forestry eco-security need to be further studied;and 3)The research on policy framework related to forestry ecological security should be promoted.
