摘要/Abstract

摘要： 为掌握甘肃森林生态安全状况,查找影响森林安全的主要原因和突出问题,针对性开展改善森林经营措施,提高森林生态功能,发挥森林在生态安全屏障建设中的主体作用。本文结合压力-状态-响应(PSR)模型,建立甘肃省森林生态系统的压力-状态-响应指标体系,根据甘肃省年度森林资源连续清查及历年统计年鉴数据,采用熵权法和生态安全指数法对甘肃省森林生态安全状况进行了动态定量评价,得出了甘肃2006-2015年森林压力、森林状态、森林响应和综合评估指标趋势。结果显示,甘肃省2006-2015年期间内森林资源自身健康水平得到提升,森林生态系统整体安全状况的综合评估值呈逐年上升趋势,森林生态系统安全状况得到较大改善。并在此基础上,提出了针对性的对策建议。

Abstract: The aims of this study were to analyze forest ecology security in Gansu Province, and to identify the main factors that positively and negatively affect the security of forest ecology. The ultimate aim is to improve forest management and the ecological function of forests in this region. Based on the Pressure-State-Response (PSR) model, we established an index system for the ecology of forests in Gansu Province. The security of forest ecology was determined by dynamic and quantitative evaluations using the entropy weight method and the ecological security index method, using data from the annual forest resource continuous inventory and the Statistical Yearbook for Gansu Province. The results showed that forest health has improved in Gansu Province during the period of 2006 to 2015. Also, a comprehensive evaluation of the overall ecological security of forest ecosystems showed an increasing trend from year to year, and the security of the forest ecological system has improved greatly. We discuss countermeasures and forest management strategies based on these results.
