内蒙古锡林郭勒盟的草场承载力与畜草平衡分区

本文根据气候潜力推算出锡盟各旗县的草场承载力。并与实际载畜量的对比,将锡盟划分为4个亚区,进而探讨了各区发展畜牧业生产的途径。认为必须增加草场投入,逐步形成以集中养畜为主的现代生产方式,在高水平的畜草平衡关系上发展畜牧业。同时要限制开垦草场、开展区域协作、加强人口控制。

THE CARRYING CAPACITY OF GRASSLAND AND THE PARTITION ON THE LIVESTOCK AND PASTURE BALANCE IN XILINGOLE LEAGUE,INNER MONGOLIA

Based on the correction of temperature and moisture to the potential photo-synthetic productivity, the paper calculates the climatic yield and availableyield in Xilingole League.The league is divided into 4 subregions accordingto the balanee between the livestock's amount and pasture yield. Theauthor also discusses the problems and suggestions about the husbandry andland use in these subregions. The results show that the prospects of animalhusbandry are poor if it would only depend on the natural productivity ofthe rangeland. In order to promote the animal husbandry, a series of mea-sures must be taken in the league, such as increasing investment, improvingthe management of the pasture, limitting cultivation in pasture,developpinginter-subregional co-operation and controlling the population in the area.
