| 摘 要： | 从子午岭林区消长的历史过程出发，在分析讨论人为活动——植被变化——侵蚀产沙的基础上，应用野外调查和航片对比解译数据，分析研究了人为破坏植被的时空特点，主要方式及其与侵蚀产沙的关系，表明近期大规模人为植被破坏活动在时间上的阵性与人口增长、经营政策变化同步，植被破坏随地形部位的空间差异与加速侵蚀的发生演变密切相关，从而说明，人为破坏植被是造成森林林地面积减小的根本原因。

| Abstract: | In this paper,by analysing historical process of forest change and relation of human activities-vegetation change-ecologic response,using data from field work and contrast interpre-tation of airphoto,temperal and spatial distribution of manmade destroying forest and relationship between it and soil erosion are studied.The results have shown that manmade forest destruction is a principal factor to lead forest area decrease and ecologic environment worsening. |
