Therefore the paper recommend that the urban - rural ecotone is examined in the whole environment , concentrating on urban fringe area of different type should be gradually expanded under control , fitting the natural ecological values . based on the analysis , some ideas are brought forward about optimizing the spatial pattern of landscape in urban - rural ecotone of urumqi 最后,從整個地域單元層面上分析快速城市化對區域生態環境產生的影響,指出不合理的土地利用格局是區域生態問題產生癥結所在,缺乏協調的人為控制常常使其處于無序發展狀態。
2 land use characteristics in ecotone between agriculture and animal husbandry . this paper analyses the farmland and grassland dynamic change spatial pattern in ecotone between agriculture and animal husbandry during recent tens years . in the view of farmland and grassland dynamics pattern during ten years , the main farmland change is it shifting forest and grassland 從我國農牧交錯帶近十年的耕地、草地變化的空間格局看，整個農牧交錯帶的土地利用變化，從耕地的變化看，主要表現為耕地變林、草，以內蒙古的變化為大，主要分布于它的中、東部地區。
The study used method of analysis landscape structure to describe the difference of the two marginal regions , and with it , to expose different mode of ecological environment responding to variety of climatic and anthropic activity , which happened in two marginal regions being part of ecotone in the semi - arid or arid of the north china 試用景觀生態學中景觀格局分析方法對這種差異進行描述，通過對兩大沙漠邊緣帶土地利用土地覆蓋格局變化對比研究，力圖揭示我國北方干旱區與半干旱區沙漠邊緣生態脆弱帶生態環境對氣候與人類活動變化表現出的不同響應方式。
Based on an analysis of the history and present status of the farmland - pastoral ecotone in the northern part of china , a new point of view was proposed in this paper for the construction of eco - environmental systems , namely , the industrial structure has to be modified so as to make a functional integration between different parts of the whole system : to give priority to a combination between cultivated grassland and in - shed feeding of domestic animals , and at the same time , to employ a new model of animal husbandry so that the degradated natural grassland can be recovered ; to develop a new type of processing industry for agricultural and forestal products so as to create a pluralistic enterprise structure ; to make a better use of water resources by taking advantages of the abundant resources of energy and minerals , and to restrain the expansion of industries of high environmental cost ; to employ techniques of integration management and restoration ecology , and to speed up the process of woodland and grassland recovery ; to make a thorough plan for arrangements of hills , waters , roads , farmlands , forests and pastures in order to gain an integration at landscape level 摘要在簡要分析中國北方農牧交錯帶形成歷史和現狀的基礎上，提出了北方地區生態環境建設必須從產業結構調整出發、進行系統功能整合的思路：把人工飼草業舍飼畜牧業擺在農牧交錯帶經濟發展的優先位置，推行新型畜牧業經營管理模式，促進天然草場改良復壯；發展“綠色”農林牧產品精細加工業，建立多元化產業結構；發揮能源和礦產資源優勢，合理利用水資源，限制以破壞環境為代價的產業的發展；推廣區域綜合治理與生態恢復技術，加大退耕還林還草的力度；山、水、路、農、林、牧統一規劃，實現生態系統在景觀水平上的整合。
In the fourth chapter , we further clarify the relation between land use / land cover change and regional climate change , i . e . temperature and precipitation in changling county . as a representative region in the ecotone between agriculture and husbandry in northern china , the reduction in vegetation cover in changling county increases both the surface water flow and surface temperature 第四章在介紹土地利用變化影響氣候變化的機理的基礎上，探討了土地利用變化對區域氣溫和降水的影響，長嶺縣作為中國北方農牧交錯帶的典型區，其土地利用是向著使地表植被覆蓋減少的方向變化的，因而既增摘要加了地表徑流又使地表溫度升高。
3 eight communities are identified by gradient analysis in desert - oasis ecotone , and species are divided into 5 ecological groups . dca ordination is superior to cca and dcca . variation of vegetation explained by environmental and spatial factors reaches 23 . 4 % ; among these the species matrix explained by non - spatial soil factors account for up to 11 . 5 % of variation , spatial variation that is not shared by soil factors explains up to 11 . 6 % , their interaction explains up to 0 . 3 % 3 、通過梯度分析，阜康荒漠綠洲過渡帶群落可分為8個類型，物種可分成5個生態類型； dca排序效果優于cca和dcca ；土壤和空間因子解釋了植被分異的23 . 4 ，其中土壤因子占11 . 5 ，空間因子占11 . 6 ，二者交互作用占0 . 3 。

Species diversity dominance niche community ordination and classificationx population spatial pattern in desert - oasis ecotone in fukang , along with their relation to soil factors , are analyzed by quantitative vegetation analyze methods . the characteristic x dynamic of landscape ecological pattern and their influence factors are also analyzed by the partition of landscape transect . oasis stability is primary explored by the successive observation of soil water and salt in sangonghe basin in fukang 采用植被數量分析方法，分析了荒漠綠洲過渡帶植物群落的物種多樣性、優勢種生態位、群落排序與分類、種群空間格局，以及它們與土壤因子之間的關系；通過劃分景觀樣帶，分析了阜康土地利用景觀生態格局的特征、動態及其影響因子；通過阜康三工河流域土壤水鹽的動態觀測，對于綠洲穩定性進行了初步探索。
Based on the former research theory , the connotation of urban - rural ecotone was discussed by a case study in houma . the spatial distribution character , the scope definition and the land use character in the urban - rural ecotone were specially researched . problems in land use were pointed out and optimum design of land use structure in urban - rural ecotone was given 本文在以上理論研究的基礎上，以山西侯馬為例，通過對城鄉交錯帶內涵的辨析，著重探討城鄉交錯帶的空間地域分布特點，界定城鄉交錯帶范圍，指出城鄉交錯帶土地利用特征，找出了土地利用中存在的問題，并對城鄉交錯帶土地利用結構進行優化設計，最大限度地挖掘城鄉交錯帶土地利用的潛力，提出了城鄉交錯帶土地利用優化結構以及調整措施。
The two species with bigger niche overlapped greatly with other species , suggesting wider niche species also had bigger niche overlaps . genetic analysis of 6 subpopulations with 117 of haloxylon ammodendron in ecotone by rapd indicated 16 primers detected 74 loci , of which 71 loci was polymorphic , percentage of polymorphic loci accounted for 96 % 采用rapd對荒漠過渡帶6個梭梭亞居群117個個體進行遺傳多樣性分析，結果表明， 16條引物共檢測到74個位點，多態位點為71個，多態位點比率為96 。
The concept , scope , occurrence , development , dynamic mechanism and the influencing factors of urban - rural ecotone were discussed in this paper . to guide the land use development in the urban - rural ecotone , the principles and methods for optimal allocation of land resource were researched and the limited land resource was allocated in this study 本文通過對城鄉交錯帶概念、范圍、發生、發展、演替規律及其驅動力影響因素的研究，結合城鄉交錯帶土地利用研究的基礎理論，探討了土地資源優化配置的原理和方法，并對有限的土地資源優化配置進行了探索，以指導城鄉交錯帶土地利用的健康發展。
This research provides an analysis of the integrated mechanism of the emergence and expansion of the different types of desert lands , and compares this mechanism with the theory of ecotone . the paper discusses the relationship between ecological fragility and desertification . it concludes that with the environmental vulnerabilities , ecotone lands are easily desertified under the adverse human exploitation . because exploitation of the ecotone lands makes the environment more vulnerable , human should act to use the lands in a way compatible with the environment . the control of desertification is also discussed 在聯合國對荒漠化定義的基礎上，分析了各種類型荒漠化土地形成發展的綜合機理和環境的脆弱特征，并聯系生態脆弱帶理論闡釋了生態脆弱性和荒漠化發展的關系，認為土地的脆弱性是荒漠化的基質，人類不合理的開發是荒漠化的誘因，而荒漠化進一步使環境更加脆弱。最后給出了荒漠化治理的措施和建議。
The radical reason of lower ecosystem productivity and disharmonic developing in this ecotone is the improper configuration inner animal husbandry for example of ansai county and big animal scale exceeding the threshold of the primary productivity for example of wuchuan county , which above - mentioned leads to the fact that coupling mechanism between agriculture and animal husbandry system has not been established , and agriculture and animal husbandry is still in the state of disharmonic on the whole . 3 主要表現為兩種典型結構模式，一種以安塞縣為代表，農牧能值總體利用率較高，但畜牧業內部結構偏重食糧動物使得高質能轉化率低下；另一種以武川縣為代表，農牧業結構總體上朝趨于協調方向發展，但畜牧業規模過大，由于草畜平衡嚴重失調，導致農牧系統耦合機制難以穩定。
Steppe diversity , however , is characterized by higher plant diversity in the ecotone , especially in the forest - meadow region . diversity indices of plant communities reached peak values at the boundaries between the ecotone and the forest zone or the steppe zone , and between the forest - meadow region and the meadow - steppe region within the ecotone 在森林-草原交錯帶多樣性指數較高，表現在多樣性指數在森林-草原交錯帶與森林帶和草原帶之間以及森林-草原交錯帶內森林草甸區和草甸草原區之間的邊界不同程度地出現峰值。
Now the systematic research on land use change and construction of ecology in urban - rural ecotone lies in a preliminary phase , especially it is lack the whole development target and planning to how to maintain the complete of the district ecosystem system in rapid urbanization process 我國對城鄉交錯帶的土地利用變化及生態建設研究尚處于起步階段,尤其是在推進城市化發展中如何維持區域生態系統的完整性方面缺乏整體發展目標和規劃。
Many factors have a great effect on bird community , such as elevation , vegetation variation , type of habitat , human disturbance and ecotone . the guild is the result of competition and evolution , which is often classified according to the nesting , the foraging and the behaviour 在研究環境因子對鳥類群落的影響時，主要考慮的因子為植被的垂直格局和水平格局、植被演替、生境類型、棲息地結構、海拔、景觀破碎、生態交錯帶等。
When community developed to climax stage , however , the species diversity would decrease attributing to the disappearance of some pioneer species . in addition , species diversity of the shrub - tree ecotone would increase swingingly , due to the “ bundary effects “ 但當群落發展到成熟的頂級階段時，多樣性會隨著一些先鋒種的消失而有所下降；另外，林灌交替階段會因“邊緣效應” ，物種多樣性大幅增加。
The main results are as following : 1 species diversity indices are significantly different among communities in desert - oasis ecotone , but are low in general ; diversity indices based on important value and cover are more properly in arid desert areas 主要結論如下： 1 、阜康荒漠綠洲過渡帶物種多樣性在群落間差異顯著，總體上多樣性水平較低；對荒漠植被，以重要值或蓋度為指標計測多樣性指數較為可行。
