摘要: 本文以商都县北部为例, 对草原农垦区风蚀、沙漠化的现状, 发生、发展及其特征进行了初步探讨, 提出了该区土地风蚀、沙漠化的主要因素是在干旱多风的自然条件下, 过度开垦沙质草原导致强烈风蚀所致。并认为该区现代沙漠化的发生时间为60-70年, 沙漠化的发展则在近20-30年, 并且以较大面积的风蚀地(风蚀残丘、风蚀洼地)、粗化地表、灌丛沙堆和片状流沙为主要地表特征。本文提出乌盟后山草原农垦区沙漠化的整治应该是: 调整土地利用结构, 控制农垦, 固定基本农田, 退耕风蚀、沙漠化耕地, 还林还牧; 以农田防护林网为骨架, 进行区域性控制, 以片林堵风阻沙, 提供生物防护; 以草定畜, 防止草原过牧; 种树种草, 增加植被, 固定地表, 进行综合性治理。

Abstract: The desertification area in steppe-reclamation region in the northern part of Shangdu County has reached 1069000 mu, among which the developing desertification area is 926650 mu, the intensive developing area, 82350 mu, and the grave desertified area, 60000 mu. The desertification in this area, because of much wind and much drought, has been caused by aeolian erosion which comes from anthropogenic over-reclamation. Here the desertification occurred 60 or 70 years ago and it is only in the Past 20 or 30 years that the desertification has been developed. And now the desertification here is still growing with such Properties as: wind erosion hills and depressions, coarsened surface, shrub dunes and lamellate shifting sand. A comprehensive way should be adopted to harness and control the desertification in this area, such as: to limit reclamation, to fix the basic farming field, to grow wind-break forests, to graze Cattle by the amount of herbage and to increase vegetation by Planting trees and grass, and etc.
