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。

In this study, the northern catchment of the research site was selected. The main vegetation types included pine woodland, meadow, ecotone between hemlock forest and meadow, hemlock forest, ecotone between hemlock and spruce forest, and spruce forest.

本研究样区为塔塔加鞍部北面集水区，包括各植群与其相邻的推移带：二叶松疏林区、草原区、草原与铁杉森林推移带、铁杉森区、铁杉与云杉林推移带及云杉森林区，并於所规划集水区外选取两参考样点：二叶松森林与麟趾山草原区。

This paper reviews predecessors' understanding on ecotone between agriculture and animal husbandry,introduces the concept applied in northern China and regional boundaries of the ecotone,and points out that zonal and azonal geographic factors are accountable for the interlocking characteristics of farming and animal husbandry in landuse patterns.

在综述了前人对农牧交错带的认识后，给出中国北方农牧交错带的概念和区域界线；认为土地利用结构的农牧交错性是地带性与非地带性双重影响的结果，其空间格局有6种区域组合类型；随着人口负荷的加大，调整土地利用结构是保证这一地带生态安全与粮食安全的基本出路。

ecotone：群落交错区

导致这种水平方向上的复杂的镶嵌性(mosaicism)主要原因有以下几方面:群落交错区(ecotone)又称生态交错区或生态过渡带,是两个或多个群落之间(或生态地带之间)的过渡区域.

ecotone：交错区

水库的水陆生态交错区(ecotone)包括山地、滩地和浅水区,该区域生境异质性高,生物多样性较高. 交错区依植被类型分为森林系统、灌丛、沼泽、水生植被(挺水带、浮叶带和沉水带);依地形分为阶地、消落区、沿岸带、亚沿岸带和中央区(图7-1).

ecotone：过渡带

--土地利用/土地覆盖变化(LUCC)及其生态响应以珠江口为核心研究区,以珠江三角洲为重点区域,开展土地利用景观格局演化过程、驱动机制与环境效应研究;沿东江、北江、西江、海岸带、城乡过渡带(ecotone)等重要景观生态廊道展开梯度分析,

ecotone：群落交會帶

在我们讨论这个问题前,先说明群落交会带(ecotone)和边缘效应(edge effect). 所谓群落交会带,就是当两个基本植群或是不同演替期的植群相接触时的过渡地带,其宽度通常小於基本植群,但此带却同时拥有两植群的组成与性质. 在群落交会带中,
