【摘要】 以桂西北环江县肯福环境移民安置示范区为例，对我国西南喀斯特地区环境移民安置区的气候、地貌、土壤与植被等主要生态因子进行了调查研究和取样分析。研究表明，环境移民安置地由于地处亚热带季风气候区，具有气候温暖，雨量充沛，日照充足，且雨热同季的特点；地貌破碎，土地以坡地为主，但有一定量可开垦利用的土地；土壤主要为红壤，土壤剖面发育良好，土壤质地和结构尚可，有机质和氮含量相对丰富，但磷、钾缺乏，土壤酸度大；植被以先锋植物为主。更多还原

【Abstract】 Main ecological factors such as climate, landscape, soils and vegetation were investigated in the demonstration area of immigrant settlement in Kenfu, Huanjiang, Guangxi. The results showed that the area was characterized by warm climate, plenty rainfall, abundant sunshine, and rainy season which coincided with high temperature. The landscape was broken. Hillside fields were the main forms of land, and some of them was arable. Most of the soils were red soil. Soil profiles developed very well. The content of soil organic matter and nitrogen was abundant, but the contents of soil phosphorus and potassium were deficient. Acidity of soil is strong. The texture and structure of soils are fair. The pioneer plants were the predominant plants in this area.更多还原
