摘要: 本文采用农业气候分类与土地特征(地貌、坡度)分级相结合的方法编制云南省热区图。这是用一张图,在同一块图斑上同时表示出农业气候和土地两种专业内容特征;按土地和气候的本来面目分型划类,并量算出各类型分区域的土地面积。这是一次新的尝试,以期使科学性和实用性能较好地结合起来。

Abstract: The Yunnan torrid region located geographically in a special place with very complex topography has rich and various agricultural climate and land resources. To meet the principal demands of exploiting the torrid region, the authors have worked out a set of maps, and hope it could provide a significant scientific oasis for the authorized administrations at different levels to make proper projects when they want to exploit the torrid region.This paper has combined together two different specific contents which are agricultural climate and land. Thus you can see two specific contents in one graphic spot. The authors classify the whole region into different small regions according to the true features of the region and then draw them up and calculate out the area of each region. The method of drawing the map is as follows: At first determine a reasonable and simple classification index; Next divide the whole region into two regions as the rirst class index according to heat; Then divide them again into even smaller regions as the second class index according to water and topography as well as the land slope; At last, the whole region is divided into 30 small regions with different climate and land type. Following the above work, the graphic spot margins are drawn according to the relevant elevation, topography, siol, vegetation and so on. Finally, the map(l:500 000) is finished and the area of each region calculated.What the authors have done is a new trial among similar researches. It is hoped that it cound be useful to guiding the exploitation of the Yunnan torrid region.
