  1. There is a well - known saying in america : " securitize your dream. " aimed against the changes of international insurance industry, through the analysis of the characters and the enlarging trend of the catastrophe risk, this paper preliminarily considers on the securitization of catastrophe insurance both in theory and practices, on the basis of the discuss of the existing limitations of the traditional reinsurance towards the risk - scatter of the catastrophe insurance, using the international idea of the advanced insurance innovation and risk property - manage for reference

    美國有句名言： 「證券化你的夢」 。本文針對國際保險業經營環境的變化，通過對巨災風險的特性及其不斷擴大趨勢的分析，在論述傳統再保險對巨災保險的風險分散所存在的局限的基礎上，借鑒國際上先進的保險創新與風險理財理念，對巨災保險證券化進行了理論與實踐方面的初步探討。
  2. Abstract : the restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology. through interpreting the images of remote sensing in 1985 and 1999, the basic information of forest resources of lushuihe forest bureau, which is a typical forest area of changbai mountain, was obtained with support of gis. by dividing land covers of lushuihe area into 10 types ( water body, residential land, stump land, farming land, wetland, mature conifer forest, midlife conifer forest, mature broadleaf forest, midlife broadleaf forest, and man - made young forest ) and dividing the riparian zone into four buffers ( in turn, 1000, 2000, 3000, 4000 m away from the river ), the changes of riparian forest resources during 1985 - 1999 were analyzed. the results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved, but the riparian ecosystem was still flimsy. in buffer 1, 2, 3, the area of midlife conifer forest increased largely, but the areas of other types of land covers all decreased. midlife conifer forest had a comparatively good status in the three buffers. in buffer 4, midlife conifer forest, mature conifer forest, and mature broadleaf forest formed a forest - age rank that is helpful to stabilize the forest ecosystem and exert its functions. area percentage of wetland decreased in buffer 1, buffer 2, and buffer 3, even in buffer 4 in which forest ecosystem rehabilitated comparatively well, so protecting and rehabilitating wetland is a very difficult task

    文摘:本文對兩期遙感圖像進行解譯，並在gis支持下提取露水河林業局主要河流兩岸各緩沖區森林資源信息，經分析得到各類地物在1985年及1999年的變化趨勢.結果表明:在河流沿岸對森林的採伐強度1999年較1985年明顯減小，整體生態環境較1985年有所改善.在緩沖區1 ， 2 ， 3除中齡針葉林大幅度增加外，其它地物類型面積均減少，由此可以看出，在這三個緩沖區內針葉林得到了較好的恢復.在緩沖區4內，中齡針葉林、成熟針葉林、成熟闊葉林形成一個林齡梯隊，有利於森林生態系統的穩定與功能的發揮，十五年間緩沖區4受到的干擾相對較小.濕地數量在四個緩沖區內均有所減少，雖然在緩沖區4內森林生態系統恢復的較好，但濕地面積仍有所減少，說明保護及恢復濕地資源是一件非常艱巨的任務，必須引起高度重視.圖5表2參12

  4. 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
  5. After january, 2003, “ the law of government procurement ” came into force, both concentrative purchase and dispersive purchase are use by government, which starts an new trend of government purchase progress, using concentrative purchase to do more large quantity purchase, dispersive purchase is used less and less, it only used to do little quantity purchase. the list of government purchase has become longer and longer, the variety of materials and the quantity of materials has increased so sharply. our country ’ s government purchase has made a great progress, but but we still need to take notice of the other side of the fact, there are two important issues, the first is the obstacle of the reforming process in the field of public finance system ; and the second is the kinds of problems occurred in the process of government procurement

    政府采購制度改革是我國公共財政改革的重要組成部分，引入我國從試點到推廣實施僅有十年的時間，卻取得了巨大的進展， 《政府采購法》在2003年1月開始實施后，我國採用集中采購與分散采購相結合的政府采購方式，開始了我國政府采購的集中化趨勢進程，從早期分散采購演變為大批量的集中的采購方式，當然，小批量分散采購也結合其中，列入政府集中采購目錄的物資種類與采購數量大大增加，取得了巨大的進展，卻也存在著不少的問題，具體表現為政府采購過程中出現的各種操作性問題和政府采購制度推進的障礙，以及政府采購的環境效益問題，操作性問題和政府采購制度推進的障礙問題本質上可歸納為兩方面，即內在因素，這是事前性的，偏重於制度性、體制性等根本問題;外在因素，這是管理操作層面的因素，政府采購的環境效益問題是由政府是否采購綠色產品，推動綠色產品在社會的使用而引出的，於是，對政府采購集中化趨勢中所暴露出的問題進行分析，找出問題的根源以探尋解決的思路及對策就顯得尤為急迫。
