黑河流域生态水文过程的观测-模型-数据分析集成研究专辑前言（英文）

Research on ecological-hydrological processes in arid/semiarid environments mainly focuses on the following aspects: 1) evolution of the current environments,2) impacts of hu? man activities and climate change,and 3) sustainable development.In the last decades,with the support of China's top science and research agencies/institutes (e.g.,Ministry of Science and Technology,MOST;National Science Foundation China,NSFC;Chinese Academy of Science,CAS),multiple integrated research projects that aim to address the above issues have been initiated from both engineering and scientific perspectives.For example,supported by the NSFC's "China's Western Region Environment and Ecology Science Research Project",in China's northwest arid region,Loess Plateau region and the southwest karst region,four key research themes have been proposed: 1) evolution and development of China's western environment,2) water cycle and sustainable use of water resources,3) ecosystem sustainability,and 4) the impact of major constructions/projects on the environment.In addition,“Heihe River Basin Integrated Water Resources Management Research Project" has been the key research project supported by the CAS,which aims to improve water use efficiency,sustain the oasis ecosystem,develop the integrated irrigation water technology,improve water resources management,protect wetland and help with the river basin water management and decision making.     

基于SWAT模型的天目湖流域径流模拟分析

SWAT模型作为一种分布式水文模型已被国内外学者广泛应用于流域尺度的水文模拟分析。本文以天目湖流域为研究区,用DEM、土地利用等空间数据及CMADS中的气象数据等属性数据,在SWAT-CUP中通过率定、验证等方法,对该流域2009-2018年的径流进行了模拟。本次率定的决定系数R²为0.68,Nash-Suttcliffe效率系数NS为0.66,验证的R²为0.70,NS为0.65。率定和验证的两个评价参数都大于0.5,说明本次模拟结果较好,对天目湖流域内总磷、总氮等污染物的模拟数据进行分析是可行的,这可为当地的水资源规划和水资源可持续发展提供参考。     

滦河潘家口水库控制流域水量与污染物负荷模型构建及率定

由于水质时空监测资料缺乏,采用水文水质模型模拟的方式揭示污染物负荷的主要贡献是流域管理的重要手段。本文以滦河潘家口水库控制流域为研究背景,根据水文气象、下垫面及水质监测等数据,构建了流域SWAT水文水质模拟模型,采用实测径流和水质监测资料对模型进行参数率定和验证,结果表明：径流模拟的R²和NSE均大于0.50,尤其是潘家口水库入库径流模拟的精度在0.79以上。各水质监测断面TP模拟的R²在0.57以上,TN模拟的R²在0.61以上,说明构建的SWAT水文水质模型能够反映流域水文过程及污染物迁移转化过程,研究结果可为潘家口水库污染物来源分析及水资源管理提供科学依据。     

数字流域中的WebGIS设计与实现

研究了基于WebGIS体系的数字流域系统的建设,提出了以渭河流域为试点的数字流域建设的设计及实现方案,实现了该流域信息的可视化及地图交互操作。     

英谈村·红岩村

踏入英谈,便有一种十分亲切的感觉。这里的山,这里的路,这里的墙,这里的瓦,映入眼帘的全是红色。及至细看,整个英谈似乎都是用红色的岩石打造的,与笔者的名字暗合,于是,一股暖流由心底泛起:我这不是找到根了吗?!两个小时,随着中国景观村落评委们的脚步,我对英谈匆匆过了一遍,哎     

Analysis of petroleum hydrocarbons in mangrove sediments of Red Sea of Yemen

A field work has been carried out to identify the occurrence of oil and oil products pollution in mangrove sediment from Red Sea of Yemen. The concentration of total petroleum hydrocarbons is from 700ng/g at Kamaran Island station to 400 ng/g at Al-Hodiedah station, and the total organic carbon （TOC） in samples ranges from 0. 07% at Dhubab station to 0. 03% at Kamaran Island station. This pollution is as a result of localized oil pollution and/or heavy ship traffic in the Red Sea and Gulf of Aden.     

厦门市马銮湾流域规划中几个水文问题的分析计算

厦门市马銮湾流域规划中几个水文问题的分析计算郭逢潮（福建省水文总站厦门分站）１问题的提出马銮湾流域是厦门市规划“一环数片”中的“重要一片”，它位于厦门市西港西北隅。因厦门市规划和马銮海堤改造的需要，我们受有关部门的委托，就马銮湾流域规划中有关设计暴雨...     

内陆河流域系统降水中的稳定同位素：乌鲁木齐河流域降水中δ^18O与温度关系

研究了乌鲁木齐河流域从下游乌鲁木齐站、中游跃进桥站和源头大西沟站降水中稳定同位素与温度的关系。揭示了内陆域系统降水中稳定同位素的变化规律。在乌重木齐河流域,降水中的δ＾１８Ｏ随海拔增高而减小,δ＾１８Ｏ与温度有密切的正相关关系,说明δ＾１８Ｏ是温度的可靠指标,在乌鲁木齐河流域,局地性降水的增加影响单个降水事件中δ＾１８与温度的关系。在是桥站和大西沟站,因局地性降水增加,所以单个降水事件中δ＾１８Ｏ
