华北地区农业水土资源匹配格局分析

Analysis on the Matching Pattern of AgriculturalWater and Soil Resources in North China

华北地区作为我国重要的农作物产区,面临着农业水土资源供需矛盾的难题。基于单位耕地面积水资源量法,分析华北地区2014年—2018年农业水土资源匹配格局。结果表明:华北地区的东部农业水土资源匹配指数在0.139×10^(4)m^(3)/hm^(2)以上,处于良好水平;内蒙古中部地区农业水土资源匹配指数在0.088×10^(4)m^(3)/hm^(2)左右,处于较差水平;山西省大部分地市农业水土资源匹配指数0.139×10^(4)m^(3)/hm^(2)以下,处于较差水平。

As an important crop producing area in China,North China is facing the contradiction between supply and demand of agricultural water and soil resources.Based on the method of water resources per unit cultivated area,this paper analyzes the matching pattern of agricultural water and soil resources in North China from 2014 to 2018.The results show that:the agricultural water and soil resources matching index in the east of North China is above 0.139×10^(4)m^(3)/hm^(2),in a good level;the agricultural water and soil resources matching index in the middle of Inner Mongolia Autonomous Region is about 0.088×10^(4)m^(3)/hm^(2),in a poor level;the agricultural water and soil resources matching index in most cities of Shanxi Province is below 0.139×10^(4)m^(3)/hm^(2),in a poor level.
