以南方红壤丘陵区典型的生态环境脆弱区信丰县崇墩沟小流域为例，运用景观生态学理论，选取景观稳定度及景观异质性等景观格局指数对研究区近7a的土地利用景观变化进行综合分析。结果表明：研究区在生物措施治理等人工干扰下，2003~2010年形成了以林地为主的农林景观格局，景观结构呈异质性演变趋势，土地利用景观格局由受控于少数几个景观类型的影响正在向主导景观类型林地演变，各景观类型分布趋于集中，呈聚集型分布格局，生态环境逐步改善；生物措施等人工干扰是研究区土地利用景观格局演变的主要因素。%This paper tries to do a comprehensive analysis on the landscape pattern changes in the recent seven years with Land-scape Ecology theory, taking Chongdungou small watershed for example. This region is the typically eco-environmental vulnerable area, which lies in hilly red soil region of southern China Xinfeng County of China. The results show that: the study area under the Human-induced Interference such as biological control measures, during 2003~2010 it formed the woodland's mainly agricultural landscape pattern, and showed the Landscape heterogeneity trend. The landscape pattern is changing from under the control of a few types of landscape to the dominant landscape types of forest. The distribution of landscape types tended to be concentrated and shows the aggregated distribution pattern. The ecological environ-ment gradually improved. The research shows that artificial disturbance such as biological measures is a major factor in the evolution of landscape pattern in study area.
