| 摘 要： | 为探讨峰丛洼地农业生产活动对景观的影响,从农业生产活动对峰丛洼地水文、植被及土壤的影响及其对景观格局演变的作用等方面入手,重点分析了农业生产与景观演变的相关性,结果表明:农业生产对峰丛洼地景观格局的影响,主要是由对原始植被的破坏导致表层岩溶水循环途径的阻断及表层岩溶带产流模式的改变造成的,即地下径流转化为地表径流。农业生产活动对喀斯特峰丛洼地景观变化的作用主要是破坏了地表植被系统的稳定性,造成景观破碎,使景观均质性减弱,造成景观的逆向演替乃至出现石漠化。

| Abstract: | To explore the landscape change effects resulted from agricultural activities in peak-cluster depression area,the effects of agricultural activities on hydrology,vegetation and soil were analyzed.And then,the correlation between agricultural activities and the landscape changes were discussed.The results showed that the influence of agricultural activities on landscape pattern were main attribution to the changes on runoff model and the cycling way blocking effect of karst surface water resulted from the destruction of the original vegetation.In addition,agricultural activities also destroyed the stability of land surface vegetation that induced a fragmented landscape and reduced its uniformity,even induced in a reverse succession of landscape and karst rocky desertification. |
