昆明盆地位于云南省中部,为新构造运动作用下形成的山间断陷箕状盆地。盆地南北长60公里,东西宽约15—20公里,呈近南北向展布,由东北向西南倾斜,面积约为1070平方公里,是云南省山原中最大的坝子之一。这里人口稠密,农业发达,工业集中,人地矛盾日益突出,生态环境渐趋恶化,亟待研究解决。本文在野外考察和编制土地类型图基础之上,以呈贡县附近为例,试对该区土地类型作初步研究。
The Kunming Basin, located in the central part of Yunnan Province, is a mountain-subsidence-cutty-grained basin formed by the Neotectonic movement. The basin is 60 km long from north to south and 15 to 20 km wide from east to west. It is nearly north-south distribution and slopes from northeast to southwest with an area of 1070 square kilometers. It is one of the largest braches in Yunnan Province. Here densely populated, developed agriculture, industrial concentration, human and land conflicts have become increasingly prominent, the ecological environment is deteriorating, urgent study and solution. Based on the field investigation and compilation of land type maps, this paper takes Chenggong County as an example to study the land types in this area.
