該方案由4個工程子系統組成, ( 1 )截污工程:在岸丘橋和南州橋位置各築一節制閘(而岸丘橋工程又是首選工程) ,以封住湖泊兩頭入流,杜絕污染物進入水源地的截污工程; ( 2 )引水工程:是截污工程的配套工程,利用下游長蕩湖來補充水量,並對3個引水工程設想進行了系統分析,推薦涵管方案,同時將長蕩湖作為該市戰略水源地一併納入保護體系中; ( 3 )濕地生態處理工程:對進入蕩區前的蘆葦區進行綜合整治,發展以蘆葦為主的濕地生態處理工程; ( 4 )環湖綠色自然保護帶工程:包括建設圍湖蘆葦蕩、環湖林帶、綠色食品基地以及污泥處置。First, the basic theory of the competitiveness is analyzed, evaluating indexes which conclude relative and absolute indexes basic on the last literatures are set up. second, because the data are too many and computing time is too long, the competitiveness of science and technology of 30 areas are clustered using fuzzy clustering model, the areas of the whole nation are clustered several kinds and we can draw some conclusions of same kind. evaluating the competitiveness using single model can produce white noise, so combinational models which concluding neural network, fuzzy theory and genetic algorithm are brought forward to evaluate the competitiveness of areas which are in the same kind with fujian province in the test
本文首先分析科技競爭力的基本理論,並根據以往研究科技競爭力文獻,建立包含絕對指標和相對指標的評價科技競爭力評價指標體系,其次,針對評價福建省科技競爭力在全國范圍內的排名情況數據較多,計算時間較長的具體情況,利用模糊神經網路模型對全國30個省市自治區科技競爭力水平進行聚類分析,將科技競爭力水平接近的地區聚為一類,得出科技競爭力水平相近地區情況,而後,針對已有文獻科技競爭力評價只是利用單一模型可能產生噪聲,影響評價結果,並且主觀性較強的缺點,本文將神經網路、模糊數學、遺傳演算法等智能演算法組合,利用組合評價模型對福建省和與福建省同在一類的其它地區的科技競爭力水平進行橫向、縱向評價,得出福建省在全國范圍內的科技競爭力水平排名。Supported by remote sensing and cis, through image processing, information extracting and based on mathematic models of plural information, in this paper, some favorable gold areas in mian - ning and yan - yuan area have been predicted, and it achieved the following results : ( l ) through remote sensing image digital processing, we made high accuracy remote sensing images and image interpretion maps. constructed a geodatabase of mianning - yanyuan - xichang area, including basic data ( district. drainage, etc. ) and thematic data ( rupture, stratum, magmatic rock, etc. ). this will provide scientific evidences for work of this area in the future
並取得了以下成果: ( 1 )通過遙感圖像數字處理,製作完成了實驗區的高精度遙感影像地圖及遙感解譯圖,建立了冕寧-鹽源-西昌一帶空間數據庫,包括基礎數據(行政區、地名、水系等)和專題數據(斷裂、地層、地質體等) ,為該區進一步工作提供了科學依據; ( 2 )根據各個多元信息成礦預測模型的優缺點,分析了不同預測模型的適用條件和范圍,確定了研究區採用的數學模型。Research shows that four factors have great influence on the formation of complex rock mass. first, rock mass subjected six times of tectonic movement during long period of geo - history, each tectonic movement produced fractures and associated joints corresponding to the orientation of maximum principal stress and deteriorated the properties of fractures formed at former period ( s ). second, down - cutting of langcangjiang river produced unloading fractures
採用了四種巖體質量分級評價方案對研究區巖體質量進行了研究,這四種方案包括:工程巖體分級標準( gb50218 - 94 ) 、水利水電圍巖工程地質分類( gb50267 ? 99 ) 、巖體rmr分類( bieniawski , 1973 ) 、巖體質量指數z分級(小灣, 1995 ) 。In order to get the knowledge about public payment awareness of forest environmental services ( fes ), this paper analyze about 600 questionnaires with spss, and the result is showed as the following : ( 1 ) publics have different payment awareness to forest environmental services : the maximum is eco - tourism, then the watershed services, the minimum are biodiversity service and carbon sequestration ; ( 2 ) family income, perception of fes benefits and the moral responsibility effect participants ' payment awareness effect participants ' willingness to pay ( wtp ) directly and strongly ; ( 3 ) the recognition of fes, attitude to fes payment and fes impact range effect indirectly
摘要採用分層等距抽樣技術,並利用spss軟體對在長三角地區發放的旨在調查公眾對森林環境服務付費意識的600份問卷(其中有效問卷551份)進行統計后獲知: ( 1 )公眾對森林生態旅遊服務收費的認可程度最高,其次是水文服務,而對生物多樣性和固碳服務的支付意願最低; ( 2 )直接影響公眾付費意識高低的因素包括:家庭收入、公眾對自己從森林環境服務中受益程度的認識、公眾對森林環境服務所具有的道德責任感等; ( 3 )公眾對森林環境服務重要性的認識、對森林環境服務收費的態度、森林環境服務的作用范圍則間接地影響了其支付意願的大小。分享友人
