气候变化背景下雄安新区发展中面临的问题

Problems Faced by Construction of Xiongan New Area under Climate Change

2017年4月1日,中共中央、国务院印发通知,决定设立河北雄安新区,其目的是集中疏解北京非首都功能,探索人口经济密集地区优化开发新模式,是千年大计、国家大事。京津冀地区属于半干旱半湿润地区,气候变化对水资源和生态系统具有重要的影响。文章从以下4个方面入手,分析在雄安新区建设中应该注意到的资源环境问题,以及实现"生态优先、绿色发展"建设理念所面临的科学问题:(1)京津冀地区的气候将怎样变化;(2)气候变化影响下海河流域的水资源变化;(3)海河流域水资源状况及其人类用水的影响;(4)雄安新区建设和发展过程中所面临的环境问题。

In the April 1st of 2017, the Communist Party of China （CPC） Central Committee and the State Council issued a decision that Xiongan New Area （XNA） will be constructed in Hebei Province to evacuate and remit non-capital function of Beijing, and to explore the new model of the regional optimization in densely populated areas. This decision is millennium plan and the great national event. Jing-Jin-Ji Area is located in the semi-arid and semi-humid region, and very sensitive to climate change. In the region, climate change greatly impacts on the water resource and ecological system. In this paper, we analyze the relationship between the climate change and water resource in the region from 1951 to 2015, and issue the resource and environment conditions and scientific problems should be payed attention during the XNA construction to complete the idea of ecological priority and green development.
