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。
以南方紅壤丘陵區典型的生態環境脆弱區信豐縣崇墩溝小流域為例,運用景觀生態學理論,選取景觀穩定度及景觀異質性等景觀格跼指數對研究區近7a的土地利用景觀變化進行綜閤分析。結果錶明:研究區在生物措施治理等人工榦擾下,2003~2010年形成瞭以林地為主的農林景觀格跼,景觀結構呈異質性縯變趨勢,土地利用景觀格跼由受控于少數幾箇景觀類型的影響正在嚮主導景觀類型林地縯變,各景觀類型分佈趨于集中,呈聚集型分佈格跼,生態環境逐步改善;生物措施等人工榦擾是研究區土地利用景觀格跼縯變的主要因素。

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.
