Dynamic Changes Analysis of Forest Resource in Heyuan
摘要
Abstract
The paper aimed to study dynamic changes of forest resources based on RS and GIS at time and space aspects.From 1985 to 2004, the changes of nearly 20 years showed that forest land and afforested land areas had decreased 761.1×103 hm2and 171.2×103 hm2respectively; forest coverage rates had increased 31.7%; non-forest land areas has decreased 600.9×103 hm2; forest stock volume had grown 2 708.4×104 m3; consumption was less than growth.At the same time the paper tried to find the reasons of dynamic changes, and predicated the development direction.In space, afforested land had been distributed on the north part of Heyuan and neighboring boundary mountain area, shrub and sparse forest land had been distributed on middle area, non-forest land had been concentrated on urban heartland.关键词
