甘肃省“两西”地区草地农业现状与发展策略

Primary Discussion on Current Situation and Development of Grassland in“Two West”Region of Gansu Province

“两西”地区草地组成变坏,生产力下降,可利用面积减少和环境恶化,分析了草地退化非生物因素、生物因素和社会因素。提出了退化草地治理的原则:生态建设产业化,因地制宜与系统整治相结合,重恢复、中保护、轻利用和保持政策连续性。河西地区的目标是通过山地-绿洲-荒漠系统耦合建成具有地域特色和优势的复合型草地农业系统及其产业链,定西地区是参与建立黄土高原巨型畜牧业基地,两地区以草业为纽带建立灌溉农耕区-雨养农耕区耦合系统。

The main performance of grassland degeneration was that the components of grassland became bad, its productivity decreased, the usable grassland reduced and its environment deteriorated in Two West Region. Be- cause of the climate change ) the special terrain in loess plateau, the pest ) disease and mouse in grassland degenera- tion, industry limitation, and management problem and the influence of different situation and micro-biology, the fragility of grassland environment, barren soil and low utilization rate were caused. The principles of managing the degraded grassland were the industrialization of ecological construction, the combination of adjusting measures to local conditions and systematic management, the heavy recovery-medium protection-light utilization and continuity of policy. While its goal was to build the mountain-oasis-desert coupling system in Hexi Region and participate in the construction of Loess Plateau Great Animal Husbandry Base in Dingxi Region respectively. Two regions could be integrated to the coupling system of the irrigated agricultural region and the rainfeed agricultural region.
