云南省林地资源监测分析

基于森林资源二类调查数据，以地理信息系统为依托，采用高清遥感卫星数据、森林经营档案资料以及现地调查核实等方式，开展林地资源数据变更工作是近年来林地资源监测的主要手段。文章阐述2009—2019年10年间云南省林地变更及其林地监测结果，分析云南省林地资源变化原因及变化趋势。结果表明，林地面积增长空间已至极限，林地资源利用率逐年提高，森林质量稳步提高，人工林资源进一步扩大。

Monitoring and Analysis of Forest Land Resources in Yunnan Province

Based on the data of forest resources inventory and planning and the geographic information system, the methods of high-definition remote sensing satellite data, forest management archives and in-situ investigation and verification were used to carry out the data change of forest resources, which is the main means of forest resources monitoring in recent years. This paper expounded the forest land change and the monitoring results in Yunnan Province from 2009 to 2019, and analyzed the causes and trends of forest land resources change. The results showed that the growth space of forest land area had reached the limit, the utilization rate of forest land resources had been improved year by year, the forest quality had been steadily improved, and the artificial forest resources had been further expanded.
