摘要
我国草原沙漠化的主要发生区在北方农牧交错地区,沙漠化成因中人为因素往往占有很大的比重,如何整治?本文通过数年的草原沙漠化科学考察,提出拟实行农林牧结合,走草地农业系统的路子。并重视组建合理的农林牧结构;推行季节畜牧业;农牧交错区实行农牧结合;运用农业系统工程理论,实行科学管理等环节。这样才有望在那些地区既良好地维持生态环境,又可充分利用其自然资源,创造理想的经济效益。
Grassland deserti fication occurs where the farming areas and ranching areas overlap in northern part of China. Human activities play an important part in grassland desertification. How to control desertification? Based on many years' scientific investigation, this paper suggests to practise grassland agriculture. Following measures should be taken: (1) Formulate a reasonable structure of farming, ranching and tree planting. (2) Practise seasonal animal husbandry, (3) Impose scientific management according to the theory of agricultural engineering. All of these measures aim at maintaining ecological balance in the area and at the same time create ideal economic benefit through full use of the natural reaources.
