| 摘 要： | 利用法国SPOT5卫星遥感影像现地对照,将抚仙湖流域森林植被划分为5个植被型6个植被亚型23个森林类型并统计面积,调查统计各类森林植被的树种结构和覆盖程度,分析了森林植被特征。结果表明,抚仙湖流域森林的固土物质量为137.50×106t/a,固土价值为622.30×106元/a;涵养水源价值为506.84×106元/a。

| Abstract: | The forest vegetation in Fuxian Lake was categorized into 23 forest types of 6 vegetation sub-type,5 vegetation types based on the SPOT5 satellite images and field inventory data,and the areas were calculated for each type.The features of each forest type,such as species component and coverage rate were analyzed.According to certain evaluation criteria,the amount of soil conservation as well as the soil and water conservation value of forest vegetation in the areas amount to 137.50×106 t/a,622.30×106 yuan/a and 560.84×106 yuan/a respectively. |
