  2. 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
  3. For the construction of urban landscape and the optimization of the land use, this dissertation discusses the spatial pattern of landscape ecology and its dynamic evolution of the main areas of zhanjiang city. based on the source of remote sensing ( rs ) images in 1986 and 2000, the dissertation presents such characteristics as quantities, perimeters, areas etc. of the patches, by using the function of dealing with images and data of geographic information system ( gis ) to produce the patches of landscape types. and then, the present situation and temporal and spatial patterns of urban landscape ecology are elaborated by calculating and analyzing landscape indexes

    本文以湛江市主要建成區（霞山區、赤坎區和湛江經濟技術開發區）為研究對象，以rs軟體geoimager4 . 0 、 gis軟體mapinfo6 . 0和應用軟體excel2000為研究工具，以湛江市1986年和2000年的遙感影像為信息源，通過geoimager4 . 0對圖片進行處理后，利用gis的圖像、數據處理功能，獲取景觀要素圖斑，得出圖斑的數量、面積、周長等特徵，在此基礎上應用景觀生態學的理論與方法，計算景觀空間格局的異質性指數，通過對景觀空間格局指數的分析，探討湛江市城市景觀生態空間格局及其變化特點，分析湛江市城市景觀生態空間格局中存在的問題，並針對存在的問題，提出城市景觀生態優化的對策和措施，擬為湛江市的城市景觀生態建設和土地利用優化提供依據。
