摘要
环渤海地区,包括北京、天津两市,河北、辽宁、山东、山西、内蒙古五省。水旱灾害是该地区经济可持续发展的重要制约因素。本文采用了各省市的不稳定度Cr和灾害直接经济损失占应得GDP百分比的平均数Sp,构建了水旱灾经济损失指数Ss。研究表明,Cr高值区和Sp高值区在空间上明显错位,前者在辽宁、北京,后者在内蒙古、山西。根据Ss的区域分异和等级排序,建议应以辽宁、内蒙古、山西、山东、河北、北京、天津为序进行环渤海地区的水旱灾害防治,Ss值在3以上的辽宁、内蒙古地区为国家防止和治理环渤海水旱灾害的重点省区。
<Abstrcat> There are two cities (Beijing,Tianjing)and five provinces (Hebei, Liaoning,Shandong, Shanxi and Inner Mongolia) in Bohai Rim. Flood and drought have already restricted the area's sustainable development of economy. Using instability Cr of each province (or city) and the average ratio Sp of direct economic loss of calamities to ideal GDP, this article constructs the economic loss index Ss and sets up a series of grades. Region analysis indicates that the regions whose values are high in Cr have departure with Sp's high value areas. According to the economic loss index of flood and drought in Baohai Rim Ss, we suggest that this area's facilities to agriculture should be invested in order of Liaoning, Inner Mongolia, Shanxi, Shangdong, Hebei, Beijing, Tianjin. And the national investment focus should be Liaoning and Inner Mongolia whose Ss are more than 3.
