A comparison of present land - use between karst tableland areas and karst gorge areas——With examples from Qingzhen and Huajiang of Guizhou;
喀斯特高原与峡谷的土地利用对比——以贵州清镇和花江为例
Based on the data including agriculture population densities,population densities and natural geography factors from 76 counties in the Guizhou karst plateau,the paper mainly uses regression method to analyze the relationship between population distribution and main influence factors,and a multiple regression equation has been established.
以贵州喀斯特高原76个县市(区)农业人口密度、人口密度以及自然地理因素的资料为基础,主要应用多元逐步回归方法研究贵州省人口分布与其主要影响因子的相关关系,并建立多元回归模型,针对贵州喀斯特地区的自然地理因素分布具有一定地带性,综合研究这些地带性因素的分布特征,探讨贵州喀斯特地质条件下人口分布的自然地带性规律,其结果表明:在喀斯特地质环境条件下,受经度、纬度以及平均海拔高度之间错综复杂的相互影响关系的作用,决定了贵州高原人口分布疏密差异的态势,表现为西北部人口过密,东南部人口稀疏的空间格局,使经济、社会、生态发展也呈现出不协调的状况。
The article discusses the exact distributed areas of karst and other landscapes in Guizhou, probes into the distributed features and divides the karst and non karst landscape, It throws light on the basic fetures and differences of two big geomorphology units about karst plateau and valley by taking Meitan and Ziyun county for example.
