贵州喀斯特峰丛洼地系统土地利用与人口聚落分布

喀斯特峰丛洼地地区，每一个洼地都与周围的峰丛构成封闭的独立系统，辐聚型的物质运动导致系统内物质空间分布呈现独特的垂直同心环带结构。受地形和物质（主要是土壤）分布状况的制约，土地利用有洼地与峰丛的差别，而瘠薄分散、面积狭小、比例较低的有效土地，则使系统生产能力偏低，严重制约了人口密度的增大，使该区域人口空间聚集度低，社会经济地域系统不易形成和发展，长期处于贫穷落后的待发展状态。笔者认为，改变这一状况的关键在于改善交通条件，增加内部及内部与外部的联系性。

THE KARST PEAK CLUSTER DEPRESSION SYSTEM-LAND AND POPULATION AND SETTLEMEND DISTRIBUTION IN GUIZHOU

In karst peak-cluster depression area, a depression is combined with peak-cluster to form a close geographic system. As the result of that the mater of land surface distribute in space is obvious circular altitudinal zone structure.The land use of the depression is affected by nature structure seriously. So there are significant difference between peak and depression in land use.The productivity in peak is much lower than in depression. That has made difficult' es in population concentration and settlement in space and affected the development and economy in the area. This is the key to improve traffic codition and relation with outside.
