贵州岩溶地区的草地生态环境与草地畜牧业发展
Grasslands eco-environment and stockbreeding development in the karst areas of Guizhou province
摘要
Abstract
In the karst areas of Guizhou province, utilizing the data of Guizhou land-use and rocky desertification RS investigation, and GIS spatial analysis, 24 686. 74 km2 grasslands (67. 57% of the whole provincial grasslands) were selected in the karst areas of Guizhou province. Of these areas, 39. 77% was rocky and desertified. In last 20 years, through introduction of forage grass, domestic animal species and advanced techniques and accompanied by experimention and advocacy, we have collected a full range of experiences on modification of domestic animal species, planting and cultivation of pasture, stocking modification, rotations, and intercropping. There are various grassland resources in the karst area of Guizhou province with a good future for pasture and stock, but traditional extensive management is in domestic areas with fewer supporting facilities, and less scientific support so that the ability to face disaster, particularly serious atmosphere change is weak. The soil here is weak, with grassland degeneration. An active demand for technology such as good methods of grassland planting and cultivation, local species cultivation, animal husbandry industry technology and scientific support systems, and management maintainance for restoration of grassland ecological systems are necessary.关键词
