天然草地合理利用与改良技术

Techniques for Rational Utilization and Improvement of Natural Grazing Land

天然草地是以草本植物为主体的生物群落及其环境构成的重要生产系统,覆盖范围较大,在维护生态平衡、防风固沙、防止水土流失、防止土壤沙漠化、涵养水源、吸收二氧化碳、净化空气、调节气候、美化环境、维护生物多样性等方面发挥不可替代的作用,同时也是放牧地区草食畜牧养殖产业的主要饲料来源。该文主要分析天然草地利用存在的问题,论述天然草地合理利用和改良技术措施。

Natural grazing land is an important production system composed of herbaceous plant communities and their environment,which covers a large area,it plays an irreplaceable role in maintaining the balance of nature,preventing wind and sand,preventing soil erosion,preventing soil desertification,conserving water,absorbing carbon dioxide,purifying the air,regulating the climate,beautifying the environment and maintaining biodiversity,at the same time,it is also the main feed source of herbivorous animal husbandry and breeding industry in grazing area.This paper mainly analyzes the problems existing in the utilization of natural grazing land,and discusses the rational utilization of natural grassland and the technical measures for its improvement.
