新疆于田绿洲农业资源潜力分析及持续发展对策研究

新疆于田绿洲地处干旱内陆区,生态环境脆弱,是一个以灌溉农业生产为主的经济落后地区。着重计算分析了绿洲的光合潜力、光温潜力、光温水潜力和光温水土潜力,结果表明水分和土壤肥力是限制该区农业生产潜力发挥的主要因素,对光、热、水、土资源空间组合错位的认识有助于农作物的合理布局,为绿洲农业资源的优化配置和农业结构调整提供理论依据。尽管该区农业发展比较落后,但仍具有很大的发展潜力,主要表现在耕地资源开发、水资源利用、种植业生产和畜牧业生产四个方面,并在此基础上,对提高农业资源生产潜力实现农业持续发展的主要措施进行了讨论。

Study on Production Potential and Sustainable Development of Agricultural Resources in Yutian Oasis

ituating in the arid area with fragile eco-environment,Yutian Oasis is the poverty region emphasizing irrigated farming.Calculated results of photosynthetic,light-temperature,light-temperature-water,light-temperature-water and physical potential productivities in Yutian Oasis,indicate that water and soil fertility are the major limitative factors.To adjust the agricultural structure and to adopt advanced water saving techniques are effective measures.The agriculture development of the area is lagging,but still has large developmental potentials,such as farmland,water resources,planting and livestock production.On the basis of calculation and analysis,some proposals are put forward which can improve agricultural resources potential productivities and achieve agricultural sustainable development in this region.
