Different types of development have different threshold , according to the type of land use , we may divide the threshold into business , work office , residence , industry etc , of course , the threshold may be divided according to local real situation 不同土地利用类型的tia阈值应不同，大致可根据土地利用类型将tia的阈值分为商业、办公、住宅、工业四类，当然也可以结合地方实际情况来分类。
It will prove to be meaningful in guiding the sustainable land use and the conservation of the environment in the ailao mountain . the main results were as follows : from the perspective of time succession , the type of land use in northern part of ailao mountain has undergone violent change between 1974 2003 主要研究结果为:从时间变化上看, 1974 2003年间,哀牢山北段各土地利用类型发生了很大的变化。
In order to understand land use , the study on the land use is necessary which is important for adjusting land use structure , utilizing the land resource rationally . also , it is an important implementing for dynamic monitoring land use and controlling it effectively 土地利用类型的研究既是认识土地利用的开始，又是调整土地利用结构、合理利用土地资源，以及实施土地利用动态监测和有效控制的重要环节。
Comparing the catchments at different scales , we found that there was a common characteristic between catchments at different scales , that the more uneven the spatial distribution of land use was , the larger runoff variation and sediment variation in the corresponding catchments were 对不同尺度集水区研究发现，不同集水区具有共性，即土地利用类型的空间分布越不均匀，对应的集水区的径流和泥沙年际变化就越大。
Located in southeast of beijing , pinggu district is a semi - mountain area with abundant natural resources . being a typical metropolitan suburb , pinggu district has complicated land use type , sharply different earnings from land uses and violent changes in land use 位于北京市东北部的平谷区是一个自然资源丰富的半山区农业区县，同时也是典型的城乡交错区，土地利用类型复杂、土地比较差异显著、土地利用变化剧烈。
This paper deals with the characteristics of human - disturbed soils in harbin city . samples were collected from thirteen areas covering different types of vegetation , which was divided into four parts : park and square , public courtyard and living area , road and traffic area , nursery area 根据绿地土壤的土地利用类型，将哈尔滨城市绿地划分为公园与广场绿地、公共庭院与居住区绿地、道路交通绿地、生产绿地4个区域13个采样区。
Combining regional characteristics of baoying county , jiangsu province , the author worked on the land use characteristics of this area such as land use and its spatial distribution using landscape ecology theory , position theory , sustainable development theory and gis technology 本文围绕土地利用结构，结合江苏省宝应县的区域特点，采用景观生态学、区位理论、可持续发展理论以及gis技术，探讨该地区的土地利用类型的数量、空间和组合结构。
The land use spatial distribution pattern had a decisive impact on the inter - year variation characteristics of both runoff and sediment . the catchments , which had even land use spatial distribution , had small inter - year variation of both runoff and sediment , and vice versa . 6 集水区内土地利用类型空间分布均匀，则该集水区对应的径流模数和侵蚀模数年际变化小；反之，土地利用类型空间分布格局不均匀的集水区，径流和泥沙的年际变化则大。
According to xinluo district land use data from the manual interpretation of 1985 and 2000 ' s tm image and performing the statistics with the help of excel software , the data as the patches index , diversity index , dominance index , crush rate and fractal value is calculated and analyzed 摘要根据1985年和2000年tm影像进行人工解译，提取各土地利用类型数据，计算了研究区的斑块指数、多样性指数、优势度、破碎度、分维度及形状指数等景观格局指标，并进行分析。
This dissertation puts forward a new scheme of land use classification and sets up a new land use classification system , namely the land use industry classification system , by taking the industry function as the criterion of land use classification , according to the affinity relation between land use change and industry development change , analyzing synthetically the advantage and shortcoming of our country land use classification system , using the land classification theory and logical principium , basing on the theory and practice of land use classification system from abroad to domestic 根据产业分化与土地利用类型之间的密切关系，综合分析我国土地利用分类体系的优缺点，运用土地分类理论和土地分类的逻辑学原理，在借鉴国内外土地利用分类体系的理论研究和实践的基础上，以产业用途和功能作为土地利用分类的划分标准，提出一个新的土地利用分类方案，并建立了一套新的土地分类体系，即土地利用产业分类体系。
