论中国草地的水平分布及其地带性规律

A DISCUSSION ON THE HORIZONTAL DISTRIBUTION AND ITS ZONATION REGULAR PATTERNS OF GRASSLAND IN CHINA

中国草地的水平分布，在热量、水分、纬向、向地带性和大地形的综合影响下，表现为东南部森林地带草丛、灌草丛类草地，以纬向地带性分布为主；西北部从草甸草原、草原到半荒漠、荒漠，以偏斜的经向地带性；青藏高原草地呈现以经向分异为主导的特殊的高原地带性分布。本文概述了中国草地水平分布的地带性规律。

Under the comprehensive influences of heat, humidity and topography, the holizontal distribution of natural grasslands showed a regularity that the major types of grasslands-hassocks, shrub-hassocks varied along latitudes in SE China, and the major types of grasslands-meadow-steppe, typical steppe, semidesert and desert varied with a slight lean according to the changes of longitudes in NW China. And there is a special “Plateau Zonation” generally along logitudes in the Qinghai-Xizang Plateau. In this paper the regular patterns with horizontal distribution of natural grasslands in China were described.
