| 摘 要： | 采取3S(GIS,RS和GPS)技术和野外作业相结合的方法,研究了河南省具茨山人为干扰后植被次生演替过程。在此基础上,从宏观和微观尺度对不同演替阶段典型群落的结构变化和植被叶面积指数(LAI)动态进行分析。结果表明:乔木阶段的植被LAI均值为4.1～5.5;灌木阶段为3.0～3.7;草本阶段为1.0～1.5。部分灌木林在生长季的LAI和盖度高于乔木林。随着演替进行,群落结构也发生很大变化,乔木种类和数量逐步上升。植被系统的复杂度和稳定性不断增强,其发挥的生态功能和生态服务价值随之提高。

| Abstract: | By using 3S (GIS,RS and GPS) technology and field survey data,this paper studied the process of vegetation secondary succession after human interference in Juci Mountain,and analyzed the changes of community structure and leaf area index (LAI) at different stages of the vegetation succession from the macro-and micro aspects.The average LAI at tree stage was 4.1-5.5,at shrub stage was 3.0-3.7,and at herb stage was 1.0-1.5.The LAI and coverage of some shrubs in growth season were higher than those of trees.Wi... |
