Submersed land area including different utilizing type by sea water are calculated and the potential economic loss and population affected by the submerged disaster are assessed for no defence ， different sea - level rise and high water level. furthermore, special topic maps of fatalness of sea level rise, vulnerability of land system, socio - economic and ecological vulnerability, and defending ability are produced. the following results are combined with the basic study cell based on area source model following mathematical models of risk evaluation, considered of defence or no defence
運用海平面上升災害危險性、土地系統易損性、社會生態經濟易損性和抗災能力的數學模型，在mapinfo軟體下運行，得到該區上述四種評估因子的專題圖；並分別按照考慮抗災能力以及不考慮抗災能力兩種情況，用海平面上升災害風險評估模型融合各因子，得到遼河三角洲（盤錦市）海平面上升災害綜合風險評估圖。 -
Along with the wave of information and globalization, human being society has already stepped into the knowledge society. the knowledge society is based on the production, distribution and utilization of knowledge and information. in the new era, knowledge increasingly becomes important and to be the most sinificant resource successive to land, labor and capital, which desides the business competitive advantages. for this purpose, enterpris - es have to divert their attention to the resouce of knowledge to get advantages over others in competition in the knowledge economy. in the knowledge economy society, as the dynamic source of the enterprises " innvation, knowledge has become the most scarce resource. it is up to present knowledge storage of firm whether it can catch more opportunities and ways of resource allocation, which contributes to competitive advantages. therefore, the more and the newer knowledge is grasped and invented, the more competitive advantages can be seized. furthermore, enterprises have to maintain their sustainable capability of competition on the ground of assurance that enterprises can effectively manage the process of innovation, inspiration, disseverance and application of knowledge. thus, it is the focus of scholars in the knowledge economy to find the mechanism how knowledge plays its role in business, and to make in - depth researches on the way of knowledge development diversion, dissemination and the law of knowledge
因此，誰掌握了最新的知識，誰掌握了更多的知識，誰發明和創造了更新的知識，誰生產了包含更多知識的使用價值，誰就能在未來的競爭中取得優勢地位。進一步地，企業為實現持續競爭力，必須以知識的持續積累為條件，以對企業自身所擁有知識從發明、激活、擴散和應用整個過程的有效管理為根本保證。為此，把握知識在企業中發揮作用的微觀機理，對企業開發、轉移、擴散、利用知識的方式和知識管理規律進行深入研究，成為知識經濟時代學者們關注的熱門前沿。 -
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 。 -
