在西部大開發過程中，水電、油氣、煤炭、有色金屬等資源的開發以及基礎設施的建設，需要大量的建設資金，但由於西部地區所處的地理位置以及歷史發展等多方面的原因，所需資金嚴重不足，形成了金融的「瓶頸」制約狀況；為了有效地解決資金的供需矛盾，本文提出採用項目融資的方式解決這一問題。Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants
文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映However, people studied the riverway mainly by field survey and landform map contrast before. because of the limits of man ' s field view and complexity of field survey route, it is a difficult bottle neck for people to make synthetical analysis on geological structure, yangtze river shoal, floodplain, terrace, and microcosmic suspended load on macroscopical scale
而以往的河道研究大多數是通過地面調查和地形圖室內對比分析來研究的（少數運用航片） ，由於受人的視域范圍及調查工作路線的布置的復雜度影響，對區域宏觀尺度下的地質構造、長江沙洲、漫灘、階地及河流微觀領域的懸浮物等作綜合性的研究便成為了瓶頸。However, this natural endowment did not bring about outstanding economic growth for this area
中部地區能源發展面臨著能源利用效率不高、運輸瓶頸制約、環境污染等矛盾。From the analysis of xiamen ' s position in the district economy as well as international economy, and the present situation and developing tendency of xiamen and shipping, i analyze the restricted problem and study how to develop xiamen as an area international logistic center. the construction of area logistical center as the foundation not only benefits the optimized distribution of social resources, stimulates the reasonable allocation of national economy, helps join the national market up with international market

本文從人力資源開發的內涵入手，得出人力資源開發是經濟發展的根本保證，人力資源開發的水平影響著經濟發展的速度和水平。西北地區人口眾多，人力資源是西北地區最大優勢、最大潛力所在，同時也是制約西北地區經濟發展的最大瓶頸。Then some conclusions we could make as follows : the inferior level of population ' s education and poor traffic condition hinder the economic development severely ; there are lots of natural resources, but the methods of exploitation are unsound ; in the industry, on one hand, the traditional take most part, such as sugar factory, tea factory and hydroelectricity station, but most of th ose products quality is inferior and the ability of market competition is weak ; on the other hand, the infant industries development is very slowly ; the protruding environment problems in lincang are pollution and soil erosion
通過分析，我們可以得知本區低水平的人口素質和落後的交通條件是制約區域經濟發展的「瓶頸」因素；區內有著豐富的自然資源，但沒有從潛在優勢轉變成市場優勢；目前本區工業已形成以「糖、茶、電」為骨幹的工業結構，但產業總體發展水平低，產品質量差，缺乏市場競爭力，同時新興產業發展緩慢，開發力度不夠；由於本區以中山地貌為主，加上不合理耕作使得農業中的水土流失問題突出，工業技術的落後帶來的污染問題也在不斷加劇。95 % of water - used by agriculture come from groundwater, and it occupied 80 % of total water consumption ( 2001 ). water shortage is becoming the major obstacle of sustainable agricultural development and the key is raise efficiency of wateruse. the results of wofost model simulation showed that the yield of winter wheat was 2323 kg / hm2 under the rainfeed conditions, 5946kg / hm2 with irrigation, while the potential yield is 8485kg / hm2 with the abundance supply of light, temperature, water and fertilizer
（ 2 ）順義區農業用水的95來自地下水，農業用水占總用水量的80左右（ 2001年） ，水資源緊缺成為限制農業生產的主要瓶頸，在日趨緊缺的水資源壓力下，提高水分使用效率成為土地可持續利用的關鍵。採用wofost模型對順義區冬小麥的生產潛力及雨養條件下水分限制產量進行了模擬，結果表明：在光、溫、水、肥條件均滿足時生產潛力為8485kg hm ~ 2 ，雨養條件下水分限制產量只有2323kg hm ~ 2 。In my views, the country or region that can break the bottleneck, and find out the business pattern, suiting the development of it industry better, and meeting the requirements of information - oriented construction, will direct the future development of it industry
