针对北京地区花生、红薯种植面积增加,花生、红薯收获后裸露地块增加,冬春季易造成扬尘、扬沙,对首都大气环境带来巨大影响的现状。本文分析了京郊花生、红薯种植面积增加及其收获后裸露地块增加的原因,浅析了造成北京地区风沙天气的原因,指出除蒙古国和我国内蒙古浑善达克、科尔沁沙地以及内蒙古高原东南部坝上地区,人为过度开垦和放牧造成草原退化沙化,生态遭到破坏,形成了影响北京地区的沙源外,京郊不合理的农作物种植造成的裸露地块增加,也是造成北京地区扬沙天气的主要原因。浅析了通过合理的农作物搭配种植模式来进行冬春季花生、红薯裸露地块扬尘控制措施,指出和北京郊区相似生态的地区,冬春季裸露地块扬尘也可参照此对策,通过合理的农作物搭配种植模式来予以控制。
For the peanut in Beijing, sweet potato planting area increased, peanut, sweet potato increased exposed bare plots, winter and spring can easily lead to dust, blowing sand, the atmospheric environment in the capital has a tremendous impact on the status quo. This paper analyzes the reasons for the increase of peanut and sweet potato planting area in Beijing suburbs and the increase of bare land after harvest. It also analyzes the causes of the sand storm in Beijing, and points out that in addition to Mongolia and China Inner Mongolia Hunshandake, Horqin Sandy Land and Inner Mongolia In the dam area in southeastern part of the plateau, due to over-reclamation and grazing, grassland is degraded and desertified due to over-man-made and grazing, and the ecology is damaged. As a result, irrigated plots caused by irrational crop planting in the suburbs of Beijing have been formed, affecting Beijing area Jan sand weather the main reason. In this paper, we analyzed the dust control measures of the peanut and sweet potato exposed areas in winter and spring through a reasonable crop-planting model and pointed out the similar ecological areas in Beijing’s suburbs. The dust in the exposed plots in winter and spring can also refer to this countermeasure. Through rational crop collocation, Planting patterns to be controlled.
