摘要
针对我省人工林未成林造林地多、造林树种多、小面积、零星分布的特点,野外调查采用“访谈式调查”和“星状小班调查”,利用SPOT5卫星影像进行判读区划的方法,解决了人工林区划不准、小面积人工林不能准确判读区划被舍去的矛盾,从而提高人工林的调查质量。并利用GIS技术建立人工林档案,方便查询和统计,为林业产权制度改革提供基础数据。
According to the characteristics of planted forest in Yunnan province including many plots of unestablished stands land, many tree species for afforestation and sparse distribution, investigations by interview and sparse subcompamnent were adopted in the field work. The method of interpretation series with SPOT5 sa- tellite images solved the contradictions of incorrect series of planted forest, and deleted small area of planted forest due to incorrect interpretation series resulted from sparse distribution, Thus it improved the investigation quality, Setting up planted forest files by means of GIS technology facilitated inquiring and counting, and provided ftmdarnental data for forest property reform.
