查询词典 cordon off an area

The results showed that grassland and farmland were the main land use types of research area with obvious reciprocal transformation. Grassland was mainly transferred to farmland in 1975-1990. Farmland was chiefly converted to grassland, and grassland tended to increase in 1990-2004. The landscape diversity in the study area rose with the contagion index decreasing and fragmentation degree being intensified during 1975-2000. The advantageous patches maintained good connectivity with the increasing patch cohesion index and the decreasing landscape fragmentation during 2000-2004. The change of human interference intensity played an important role on the variation of land use structure. Land use intensity was mainly affected by the changes in population as well as national land use policies. In the following 20 years, the agriculture land area would tend to decrease, the grassland and unused land area would have a slight reduction by contrasting the increasing the forest land area notably.

结果表明，近30 a来，草地和农业用地面积在该研究区占居主导地位，并且它们之间发生着明显的相互转化。1975－1990年，草地主要向农业用地转移，1990－2004年农业用地主要转化为草地，草地面积增加；1975－2000年，研究区景观多样性升高，蔓延度指数下降，破碎化程度加剧；2000－2004年景观内优势斑块具有了很好的连接性，聚集度增大，整体景观格局破碎化程度降低；人为干扰强度的变化对土地利用结构的变化具有重要作用，土地利用强度主要受人口数量以及国家土地利用政策的影响；在未来20 a间农业用地面积会继续减小，草地、未利用土地面积将有小幅度降低，林地面积会显著增加。

Because the area is not wide, the leading industry is characterized by projects of development. The construction of the Eco-area is very important in the regional development. The Eco-area should achieve the following objectives. 1 Has perfect shelter-forest in the seacoast, clean sea beach and the greenbelt area accounting for more 50% of the total area. 2 Has the system of collection and disposal of rubbish, the system to make economize use of water. 3 In agriculture, try best to use little chemist. 4 makes the ecological the theme; lays down regulations on the tourism, cultural knowledge spreading and bodybuilding. But we should pay more attention to the disadvantages.

The main study areas are as follows: 1 The landscape classification system of the urban-rural ecotone is set up based on the studying on land-use type of urban area and rural area, and then it is used to establish a regional landscape data warehouse for deposition, modification and management; 2 A group of landscape structure and pattern indices and patch area spectrum analysis methods are used to describe the structural and heterogeneous characters of all the landscape elements from different aspects; 3 The temporal and spatial difference of the landscape pattern of main road belts of the research area are also analyzed with the same method. Their basic process and regularity of urban axial expanding of the southwestward of Shanghai City are initially knewn well; 4 According to the traits of the ecotone, the principles and basis of vegetation classification, the ecotone vegetation classification system is set up, its species constitute, community patch characters, the relationship between vegetation types and landscape categories are analyzed, meanwhile, the vegetation sample maps are made; 5 Based on above studies, some landscape ecological stratedies within the research area were discussed. The following are the results of this study

城乡交错带地区的景观分类，在对城市地区和农村地区的土地利用类型研究的基础上建立了城乡交错带的分类体系，并在此基础上用ARC＼INFO软件分时段、分区、分要素建立研究区的景观图形数据库，对数据进行存储、修改和管理；2）利用多种景观结构、格局指数和斑块面积谱分析方法，从不同的侧面对各种景观组分的结构以及区域的景观格局特征进行了分析，并对其成因进行了探讨；3）利用相同的分析方法，分析了城乡交错带中的城市干道两侧的景观格局特征的空间和时间分异情况，初步掌握上海城市西南轴向扩张的基本过程和规律；4）对城乡交错带中非独立的景观要素-植被，研究其遥感图象信息的基本特征，建立适合区域特点的植被分类体系，并在样区中建立了植被图形数据库和计算机制图，分析了植被景观种类组成、斑块等级等特征以及与不同景观的相互关系；5）在上述研究的基础上，对研究区内的景观生态对策进行了研究。

Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.
