natural pollution source
解釋
天然污染源-
As the agricultural nfs is the most important factor for water environmental deterioration and lake eutrophication in china, more and more scientists and technologists focus on the control countermeasurc and pollution mechanism of agricultural non - point source ( nfs ). based on the investigation of natural resource and agricultural distribution, the loss rule of nitrogen and phosphorus in the typical land of qiandao lake watershed and distribution rule of the phytoplankton and physico - chemical characteristic in the lake were studied, and the input loading of nitrogen and phosphorus was also calculated by the annagnps model in this thesis. according to the routine monitoring data of the water environment in qiandao lake from 1989 to 2001, the concentrations of toxic substance and heavy metal were under the monitoring limit, but the total nitrogen ( tn ) and total phosphorus ( tp ) were much higher than the criterion for lake and reservoir
本文調查了千島湖流域的自然資源和農業生產情況，研究了典型坡地降雨徑流中的氮、磷污染物的輸出規律，利用annagnps模型估算流域農業非點源污染物輸入負荷，並在千島湖內設點采樣，對水質理化指標和浮游植物群落進行系統的研究，得出以下結論： 1989 2001年間的水環境常規監測資料統計分析表明，有毒物質和重金屬濃度長期在監測下限內， no _ 2 - n 、 no _ 3 - n 、 nh _ 3 - n年平均濃度均符合類標準，但湖泊水庫特定項目tn和tp濃度分別為超類和類，呈嚴重超標狀況，湖區主要污染因子是將導致富營養化的物質tn和tp 。 -
The registration orchard uses the water source and the soil achieved the non - pollution standard, simuitaneously completely uses the natural biological organic fertilizer which produces by our farms

The paper, by using the technology of gis and the method of systems engineering, analyzed the development situation of regional society and economy, the natural physical conditions, the situation of pollutant, and density distributing characteristics of pollutant, then set up the echoing relationship between pollute source diffusion and quality of air environment, which could make controlling index of pollution source discharging be closely linked with the quality of environment
本研究採用gis技術，利用系統工程的方法根據區域社會經濟發展狀況、自然地理條件、污染源狀況及污染物濃度分佈特徵進行綜合分析研究，研究建立了污染源擴散與大氣環境質量的響應關系，將污染源排放控制指標與區域的環境質量直接掛鉤。 -
Sustainable development has become the goal of struggle for human being, and it is the strategic selection of each country in world. the advancement of conception of sustainable development marks that human being ' s idea of increase and development has gotten into a new stage. in order to resolve the problem of environment and development at all, the current form of production and model of consume must be changed. being the basic unit of activity of social economy, enterprise groups are not only the user of natural resource, but also the source of industry pollution. so it should be the main part of implementing sustainable development strategy
企業作為社會經濟活動的基本單位，既是自然資源的利用者，又是工業污染的源頭，也應是可持續發展戰略的實施主體。而企業集團作為由眾多成員企業組成的有機群體既是一個巨大的投入產出系統，又是一個大型的耗散結構體。可以說，企業集團既對環境具有極強的破壞力甚至毀滅，也有對環境巨大的、潛在的改造力與更新力。
