山西省水资源开发利用对策措施

通过对山西省水资源状况及面临的水资源形势分析，提出了山西省水资源开发和利用的对策。山西省在未来10年内水资源开发利用应继续遵循“西引黄河，东抓蓄调，腹部盆地节调并举”的战略思想，只有加强以农田水利为重点的农村基础设施建设，继续抓好大中型水利工程的立项建设，鼓励支持社会各方力量兴办中小型水利工程，加强农业节水工程建设，推广农业高效用水技术，才能使山西省大部分地区的水资源短缺状况将得到极大改善，为全省国民经济和社会可持续发展提供支撑和保障。     

吉林省中部地区水资源配置初探

中部地区水资源总量为39.61亿m3。城市用水与农业、生态用水矛盾突出,城市供水能力不足,水污染问题严重,地下水超采严重,水资源开发利用不协调。该区水资源已无进一步开发利用的潜力,需通过调水工程解决缺水问题。水资源配置思路为从地处松花江上游的丰满水库引水,增加供水能力。

Optimal Locations of Groundwater Extractions in Coastal Aquifers

A regional water supply management model for coastal aquifers was developed. One of its outcomes is the definition of the optimized locations for groundwater withdrawal. Such a tool permits the analysis of alternative plans for groundwater extraction and the sustainable use of water resources in a coastal aquifer subject to saltwater intrusion. The principal components are the evolutionary optimization and the analytical/numerical simulation models. The optimization technique looks for the best well locations taking into consideration the economic results and the satisfaction of the societal water demand. However these two concerns are conditioned by trying to control the saltwater intrusion, i.e., preserving the environmental equilibrium. The simulation model uses the governing mathematical equations for groundwater movement to find the interface between freshwater and saltwater. Because of the non-linearity in the system and the possibility of a jumping interface, a security distance was defined. This is a controlling variable which can be set by the decision makers. The model was applied to a typical case with interesting results. For example, diagrams showing the relationship between the location of the wells and the security distance(s) are of importance to the managers. It was also crucial to have an understanding of the tradeoffs between groundwater withdrawals, positions of the wells from the coast line, and the security distance. The model was also applied to a real case in order to relate the extractions, distances and artificial recharge (not presented in this paper).     

浅谈京津冀都市圈区域水资源战略

京津冀都市圈区域发展已纳入国家整体发展战略，在全国占有十分重要的地位。但京津冀都市圈面临着水资源缺乏、生态恶化、水污染等一系列水问题，严重影响了区域经济社会发展。针对存在的问题，要构建区域新型水资源配置格局，提高城乡供水保证率；积极建设节水型社会；加快农村水利基础设施建设，解决农村居民饮水安全：加强水生态系统保护与修复；做好饮用水水源地保护和水功能区管理；做好跨省河流的水量分配。     

环境资源负外部性与产权理论的新进展

环境资源共有产权的特性使得社会成员只能通过自身感知和理解确定对环境资源的产权边界，并且产权的实施是非排他的，所以与环境资源有关的负外部性较其他具有直接因果关系的外部性特殊。在治理这类负外部性的过程中，产权理论也有了新的发展。本文从分析环境资源产权的特殊性入手，对于产权弱化、产权分割、创建新产权和自愿合作基础上认知产权调整等负外部性内部化理论进行了分析。
