There are complicated geomorphology shapes and various types of land - use in jiuyuan , baotou , which lies in the urban and rural transition zone of borderline discipline of baotou city 包头市九原区地貌形态复杂，土地利用类型多样，农林牧交错特征明显，而且处于包头市边缘区城郊过度地带。
Patch of dissimilar land use types had different spatial graph character , and patch of the same land use type also exhibited different spatial shape in different evolvement phase or in different environment 不同土地利用类型斑块有不同的空间图形特征，同一土地利用类型斑块在不同演化阶段或处于不同环境中其空间形状也有差异。
This is because the more diversified and even the land use structure is , the less the degree to which the several main land use types thereof dominate the entire object studied and the smaller the dominance index 这是因为土地利用结构越多样化、均匀化，其主要几种土地利用类型对整个研究对象的控制程度就越低，优势度指数也就越小。
Analysis of concentration is mainly used to discover the degree of concentration of area allocation of various land use types at the area studied and the degree to which the main land use types dominate the entire area studied 集中性分析主要用于揭示研究区各土地利用类型面积分配的聚集程度及主要土地利用类型对整个研究区的控制程度。
The region in the sand region had a totally different general characteristic for land use spatial distribution pattern from the region in hilly and ravine region , and the pattern also had some variation at different scales 风沙区和丘陵沟壑区决定了土地利用类型的空间分布格局的总体特征，不同空间尺度的土地利用类型分布特征有差异。
For landuse classes that are difficult to be directly extracted from images , we employed gis data processing capabilities with the ancillary data acquired from various sources as well as through the image interpretation processes 对于难于直接从图像中提取的土地利用类型，我们利用了gis资料处理能力和从各种资料源及通过图像解译过程获取的辅助资料。
The land use status of 1994 and 2002 in wangdonggou watershed of changwu county is analyzed , the main land use change styles and the spatial pattern characteristics of land use changes in recent years are explored 摘要对王东沟流域1994年和2002年的土地利用现状进行了分析，揭示了近几年来该区土地利用变化的主要类型及各种土地利用类型的空间格局变化特征。
The result also indicates that the influence power of the wind subsides to desertization with the gradual reduction of the number of sand - blowing winds on one hand . on the other hand , the number of sand - blowing winds , esp L ，比例较低；而耕地和林地两种土地利用类型的沙漠化稳定面积所占比例较低，发展与逆转面积大起大落，且发展面积比逆转面积大许多。
The main contents are as follows : ( 1 ) the database has been established on the need of data analysis , processing images , extracting the correlative information by rs , gis and other technologies 具体内容如下： ( 1 )利用rs 、 gis等技术手段，处理图形资料，提取相关要素：植被类型及其分布，土地利用类型及其面积、生物量分布等。按照数据分析的要求，建立数据库。
The paper uses the theory and method of markov chain to construct the transition probability matrix of land structure and predict the land structure in 2010 and 2020 , and analyzes the features of land structure transition 运用马尔柯夫链的理论与方法，构建1996 - 2004年间扬州市土地利用类型转移的概率矩阵，预测扬州市2010和2020年的土地利用结构，并分析了其变化特征。
