Study On Environment Protection Planning On Centralized Water Supply Source In Yangling City

The study explores the general situation of geographic environment and source of drinking water source. On the basis of relevant state policy, the paper makes special environment protection planning for centralized water supply source in Yangling City, puts forward first and second class protection region scope and coverage of three water sources in Yangling region, works out environment protection project plan for drinking water source. Besides, the paper makes feasibility analysis and benefit assessment to ensure the city's pollution-free water supply source and sustainable development of Yangling Agricultural Hi-tech Demonstration Zone(see detailed planning in appendix).Yangling Demonstration Zone is located on the first class development axis of state macro economic planning, belonging to traditional Guanzhong Plain Economical Zone and key node city on Guanzhong Hi-tech Industry belt and Spark Industry belt. Yangling, with agriculture hi-tech development and demonstration as its guide, boasts advanced third industry such as agriculture hi-tech education, tourism, business and commerce, enjoys the reputation as china's agriculture "silicon" with sustainable development, convenient transportation, up-to-date information, ecological and pastoral mode, a perfect combination of city and countryside and modern ecological scenery. Yangling city is also the central regional city in Guanzhong Plain.In recent years, deterioration of water quality in Weihe River has not been solved fundamentally, which poses obvious threat to earth surface water in Guanzhong region, as a result, earth's surface water and underground water quality in Yangling city has also been affected. In addition, since Yangling Demonstration Zone has maintained fast development momentum, production and domestic waste water discharge amount has increased dramatically, and underground water quality is going from bad to worse, the city's drinking water source and the danger of surrounding environment pollution has multiplied, as a consequence, the safety of residents drinking water has been challenged. The plan, based on " Eleventh Five " national economical overall planning of Yangling Demonstration Zone, with reference to relevant environment protection criteria and technical guide, designs scientifically and rationally drinking water source environment protection plan of the city, which will have far reaching effect on ensuring continued development of water source in Yangling region and its sustainable economical development, and will provide scientific basis for Yangling government's macro decision and water source safety management.The paper includes six chapters. Chapter one gives a brief introduction of Yangling city's drinking water source; chapter two illustrates the principle, basis, scope and objective of the plan; chapter three introduces the classification and approval of drinking water source protection zone; chapter four evaluates environment quality of drinking water source; chapter five proposes environment protection plan of drinking water source; chapter six makes an assessment of project feasibility, investment and benefit, analyses and summarizes project plan and guarantee of project implementation.
