云南山地民族社区环境异质性与土地利用及其生态学效应

环境异质性与土地利用/覆被变化及其生态效应研究是景观生态学研究中的前沿性课题。为揭示云南山区环境异质性与土地利用及其生态效应之间的相互关系,采用生态学和民族学等学科交叉研究的方法,以云南山区少数民族行政村为研究对象,以遥感、地理信息系统和全球定位系统（3S）技术为平台,对直苴村的海拔、坡度、坡向、土壤类型与土地利用及其生态学效应等方面进行研究。结果表明：直苴村环境异质性直接或间接地影响着区域土地利用方式,并产生一系列的生态学效应。研究为云南山区建立资源节约型和环境友好型社区提供科学依据和基础数据,同时进行相关的理论探索,为建设和谐的社会主义新农村服务。

Environmental heterogeneity and land use and ecological effects in mountainous communities of minority nationality in Yunnan province

The research on the ecological effects of environmental heterogeneity and land use/cover change is the forefront of scientific research in the study of landscape ecology. The interrelation among altitude, slope gradient, slope aspect, land use and ecological effects was studied by using the methods of ecology,ethnology and the platform of ＂3S＂ （RS, GIS, GPS）with reference to Zhiju village for the exploration of the interrelation among environmental heterogeneity and land use and ecological effects in mountainous regions in Yunnan Province. The results show that there is direct or indirect interrelation a- mong environmental heterogeneity and land use and ecological effects in Zhiju village, which provided scientific basis and basic data for the building of resource - saving and environment friendly community, and explored the related theory giving service to the building of the new socialist countryside in perfect harmony.
