The sustainable utilization evaluation of regional mineral resources this text regards laiwu ( in the middle of the shandong province , the east hillfoot of mount tai ) as a district of studying , so do maplnfo as workbench . by the present situation analysis of mineral resources , 19 indexes are chosen to form the evaluation system of the mineral resources sustainable development , they are fund tax rate , worker per capita incomes , rehabilitation rate , sloping rate , the ratios between reserves and extraction , tailing utilization ratios , atmosphere quality , water quality , economic - societies coordinate coefficient , etc . according to the experts , the quantitative indexes are quantified 2 、区域矿产资源可持续利用评价本文以莱芜市(位于山东省中部，泰山东麓)为研究区，以mapinfo为工作平台，通过对矿区矿产资源开发现状分析，决定选择资金利税率、职工人均收入、塌陷土地复垦率、采区回采率、储采比、尾矿利用率、大气环境质量、水环境质量、经济社会协调系数等19个因子，组成矿区可持续发展评价的评价因子，根据专家赋分值将定量因子进行量化，用模糊数学的方法对数据进行处理，使它们具有可比性。
Second , based on the characteristic of the receiving water studied in this paper , develope a dynamic one - dimension water quality model for nanbei river in zhangcha town of foshan city , and develope a program of water quality model based fortran powerstation . and then , calculate the concentration of codcr in receiving water using the simulation results of swmm and analyze the effect on the environment of receiving water by intercepting ratio . at last , the construction investment and operational and administrative expenses of intercepting trunk sewer 、 pumping station and sewage farm is calculated and the relation between them is discussed 其次,本文根据研究区受纳水体的特点,建立了佛山市张槎镇南北大涌的一维非稳态水质模型,相应地开发了基于fortranpowerstation平台的水质模型计算程序,并在swmm模型模拟结果的基础上,利用本文编制的水质模型程序计算了不同截流倍数时南北大涌codcr浓度的时空变化过程,分析了截流倍数对河涌水环境质量的影响。
After pointing out the econologic problems of yangtz basin , such as water and eil erosion , sediment disposal , flood damage , and degradation of water qulity , this thesis analyses the relation between sichuan hydroelectric power exploitation and construction of econologic screen in upper region of yangtz 本文就四川水电开发与长江上游生态屏障建设作了分析，指出目前长江流域存在水土流失、泥沙淤积、洪涝灾害、水环境质量日趋恶化等问题及长江上游生态屏障建设的重点。
The water resource is the indispensable natural resources of human production and life , is the environmental resources that the living beings depended on for existence too , as aggravation of the crisis of water resource and water environmental quality worsen constantly , water resource shortage has already developed into one of the resources environmental question that the world is paid close attention to extremely 水资源是人类生产和生活不可缺少的自然资源，也是生物赖以生存的环境资源，随着水资源危机的加剧和水环境质量不断恶化，水资源短缺已演变成世界倍受关注的资源环境问题之一。
Article 16 with regard to water bodies where the standards for water environment quality established by the state still cannot be attained although the discharge of water pollutants has conformed to the discharge standards , the people ' s governments at or above the provincial level may institute a system for control of the total discharge of major pollutants , and a system for making an estimate before deciding on the quantity of major pollutants to be discharged by an enterprise that is charged with the task of reducing its discharge 第十六条省级以上人民政府对实现水污染物达标排放仍不能达到国家规定的水环境质量标准的水体，可以实施重点污染物排放的总量控制制度，并对有排污量削减任务的企业实施该重点污染物排放量的核定制度。
Based on the comprehensive and systematic investigation and monitoring results made in recent years of environmental quality in the yellow river delta ( yrd ) wetland , the types and distribution of wetland have been made clear , the environmental quality of atmosphere , rivers , reservoirs , lakes and shallow sea waters in the area has been studied , and so has the wetland ecosystem 摘要调查了黄河三角洲湿地类型及分布，重点对三角洲环境空气质量、地表水环境质量、湖泊水库水环境质量、浅海湿地水环境质量和湿地生态系统现状进行了调研。
Lake surrounding economic zone : the zone is a dryland part within the proposed ecosystem function area , which has the potential to develop eco - economic , protect the water quality in the ecosystem function area , to control eutrophication and water quality deterioration , and to regulate inner land flood 环湖生态经济区：在生态功能保护区规划区域内的陆域部分，具有发展生态经济、保护生态功能区的水环境质量，控制湖泊富营养化和水质恶化，以及调蓄内涝的生态功能。
According to the fuzziness of the water environmental quality evaluation , by making good use of 1994 ~ 2004 the water environment monitoring data of shandong province , the paper adopts the fuzzy comprehensive evaluation method to evaluate the water environmental quality of shandong province ' s main river - lakes and reservoirs 摘要根据水环境质量评价中的模糊性，本文利用1994 ~ 2004年的山东省水环境监测资料，采用模糊综合评价方法，对山东省主要河流、湖泊和水库水质进行了定量评价，得到与实际相符的结论。
