摘要为探究不同地形因子对土地利用类型空间分布的影响，以连云港市中心城区 为例，以土地利用数据和 DEM 数据为基础数据，在 ArcGIS9。3 的支持下，分别 从高程和坡度两个方面对 DEM 数据和土地利用数据进行 Identity 处理，分析出 分布特点；利用它们在高程和坡度下的分布指数，确定不同地类的优势分布区； 同时利用 SPSS 软件进行双变量分析，定量认识高程和坡度对土地利用的影响程 度。研究结果表明：连云港市中心城区的土地利用与人类活动规律基本相符。第 1 高程区（0~100m）和第 1~2 坡度区（0~6°）的主要地类有耕地、园地、住宅用 地、采矿用地、水域及水利设施用地和其他用地；林地主要分布在第 2 高程区（100~200m）和第 4 坡度区（15~25°）；耕地是第 1 高程区（0~100m）和第 1~2 坡度区（0~6°）的主导土地利用方式，而第 2~6 高程区（>100m）和第 4~5 坡度 区（>15°）以林地为主；耕地、采矿用地、住宅用地、交通运输用地和水域及水 利设施用地的优势区位于第 1 高程区（0~100m）和坡度小于 6°的区域，园地和 林地的优势分布区是坡度大于 6°的区域；由相关系数可知，在高程和坡度之间， 对研究区内不同地类的分布影响比较大的是坡度。从而得出，土地利用在空间上 的分布和地形因子关系密切，并呈现一定的特征和规律性，本文的研究结论也有 助于进一步优化该研究区的土地利用结构。该论文有图 5 幅，表 8 个，参考文献 12 篇。72229

Correlation Study on Terrain and Land Use Type

Abstract To explore the impact of different terrain factors on the spatial distribution of land use types, the author takes the city center of lianyungang as an example, based on the land use status and DEM data, with the support of ArcGIS9。3, the terrain and the land use data are identified respectively from the two aspects of elevation and slope, then analyst the distribution characteristics。 Use distribution index under the elevation and slope to identify the advantageous distribution area of different land use types; at the same time, by using SPSS software to quantitatively study the effect of elevation and slope on land use。 The results show that: 1) the land use in the center of lianyungang city is basically consistent with the regulation of human activities, cultivated land, garden land, residential land, mining land, water transportation and water conservancy facilities and other land mainly distributed in elevation 1 area (0 ~ 100 m) and 1 ~ 2 slope zone (0 ~ 6 °)。 Forest land is mainly distributed in elevation area (100 ~ 200 m) 2 and 4 slope area (15 ~ 25 °); 2) cultivated land is the dominant way of land use in 1 elevation area (0 ~ 100 m) and 1 ~ 2 slope zone (0 ~ 6 °), and the dominant way of land use in 2 ~ 6 elevation area (> 100 m) and 4 ~ 5 slope zone (> 15 °) is forest land; 3) the advantages of distribution area of cultivated land, mining land, residential land, land for transport and water transportation and water conservancy facilities are located in the elevation 1 (0 ~ 100 m) and less than 6 °slope area; the advantageous area of garden and forest land are located in the region of which the gradient is greater than 6 °; 4) the correlation index shows that, with respect of elevation, the slope has much influence on different types of  land distribution。 Thus, the spatial distribution of land use and topographic factors are closely related, and present some characteristics and regularity。 The research conclusions of this paper can also help to optimize the land use structure in the study area。 The paper refers to 5 pictures, 8 tables, 12 references。 地形地势与土地利用类型相关性研究:http://www.youerw.com/guanli/lunwen_82151.html
