【摘要】：我国的干热河谷光热资源充足,干湿季分明,蒸发量大,适合发展热作、反季节作物和立体农业,但干热河谷地区的农业面源污染问题也需要引起足够的关注,特别是防治干热河谷地区农业面源污染的技术和方法。从这个角度出发,以我国干热河谷地区农业面源污染为讨论对象,从种植业和养殖业两方面介绍干热河谷地区农业面源污染现状,分析了干热河谷地区农业面源污染形成的一般性原因和特殊的地方性原因,并针对其污染原因,讨论了各种传统的和新兴的农业面源污染防治技术研究进展、应用于干热河谷地区的可行性和前景,以期防治干热河谷地区的农业面源污染。
[Abstract]:The dry and hot valleys in China are rich in light and heat resources, with distinct dry and wet seasons, large evaporation, suitable for developing hot crops, off-season crops and stereoscopic agriculture. However, the problem of agricultural non-point source pollution in dry and hot valley areas also needs to attract sufficient attention. Especially the technology and method of preventing and controlling agricultural non-point source pollution in dry hot valley area. From this point of view, taking agricultural non-point source pollution in dry and hot valley area of China as the object of discussion, the present situation of agricultural non-point source pollution in dry hot valley area is introduced from two aspects of planting and aquaculture. This paper analyzes the general and special local causes of agricultural non-point source pollution in dry and hot valley area, and discusses the research progress of various traditional and emerging agricultural non-point source pollution prevention techniques, aiming at the causes of agricultural non-point source pollution. The feasibility and prospect of its application in dry and hot valley area are discussed in order to prevent agricultural non-point source pollution in dry hot valley area.
