全球变化对区域水土资源与环境质量的影响 夏星辉;鲍振鑫;霍守亮;徐影;严登华;黄巧云 【期刊名称】《中国基础科学》 【年(卷),期】2017(019)006 【摘 要】水土资源是人类赖以生存的物质基础,是保障国家水安全和粮食安全的根本;水土资源的优化配置已成为全球生态环境保护和经济发展共生的有效途径. 在全球变化背景下,水资源的水质水量以及土地资源的格局和土壤环境质量都将发生深刻的变化. 因此揭示全球变化对区域水土资源和环境质量的影响,预估全球变化背景下区域水土资源和环境质量的变化趋势,并将这种影响纳入水土资源优化配置模型中,建立全球变化背景下规避生态环境风险的水土资源优化配置模型是当前国际研究的重大热点和前沿命题,是我国亟需解决的国家重大需求. 未来相关研究需以全球变化背景下大气—陆面—水文—环境过程演变为主线,需重点研究4 项内容:水土界面物质能量迁移传输和相互作用过程及规律分析?区域水土资源空间网络系统变化特征和驱动机制?气候变化对区域水土资源和环境质量的影响评价?全球增暖1. 5℃ /2℃区域水土资源优化配置模式设计.解决3 大科学问题:气候变化背景下水土界面物质/ 能量迁移转化过程及规律?区域水土资源空间网络系统对全球变化的响应过程及机理?全球变化背景下水土资源优化配置原理及环境风险规避机制.%Water and land resources, as the fundamental of protecting the national water and food security, are the material basis of human survival. Optimal allocation of water and land resources has become the effective ap-proach to the mutualistic symbiosis of global ecological protection and economic development. In the context of global change,water quantity and quality as well as the land use pattern and land quality will experience pro-found changes. Therefore, revealing and predicting the influence of global change on regional water-land re-sources and environmental quality,adding the influence as model scenarios and establishing the optimal alloca-tion model of water and land resources under global change to alleviate the ecological risk, are the major hotspots and frontier research worldwide as well as im-portant national demand which need to be solved. Fu-ture studies should focus on the evolution of atmospher-ic-terrestrial-hydrological -environmental processes. Four contents are put forward as key research including analysis on the process and rule of energy migration and interaction in the water-land interface; characteristics and driving mechanism of regional spatial and temporal variations in water and land resources; the influencing assessment of climate change on regional water-land re-source and environmental quality; the model design of optimal allocation of water and land resource with tem-perature increasing 1.5℃/2℃. Three major scientific issues should be solved, which include: the migration and transformation process and rule of material/energy in the water-land interface under climate change; the influencing process and mechanism of climate change on regional water and land spatial network system;optimal allocation of water and land resource and the environ-mental risk avoiding mechanism under global change. 【总页数】6页(P30-35) 【作 者】夏星辉;鲍振鑫;霍守亮;徐影;严登华;黄巧云 【作者单位】北京师范大学环境学院/水环境模拟国家重点实验室,北京100875;水利部交通运输部国家能源局南京水利科学研究院,南京210029;中国环境科学研究院,北京100012;国家气候中心,北京100081;中国水利水电科学研究院,北京100038;华中农业大学,武汉430070 【正文语种】中 文 【中图分类】X5;TV21 【相关文献】 1.全球变暖对中国区域相对湿度变化的影响 [J], 卢爱刚 2.作物种植变化对资源与环境影响的能值分析:以湖北省1978—2015年作物种植变化为例 [J], 曾琳琳;李晓云;黄玛兰;王娜 3.透视地球工程对全球陆地气候变化趋势和波动特征的影响及区域差异 [J], 孔锋 4.“全球气候变化对气候灾害的影响及区域适应研究”项目启动会在京召开 [J], 邵玉娴 5.世界水土保持学会:关于采用水土保持措施减缓和适应全球气候变化的倡议书 [J], 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.dywdw.cn/838ed045a11614791711cc7931b765ce04087a59.html
