The problem is partial waste,extensive using,impropriate lots of infield and so on in the expanding of constructive land.

城镇建设用地的空间扩展日益成为现在乃至将来土地利用变化的主要特征。

The vegetation can be classified into 4 vegetation type groups,7 vegetation types and 20 formations.Sparganium stoloniferum community and Menyanthes trifoliata community are first recorded in China.

湿地向农田等其他的土地利用类型的转变，在地区和全球尺度上都产生了很深刻的生态影响，对资源利用者来说也有显著的社会和经济影响[3]。

The problems include mixed pixel, shadow, metameric substance of same spectrum, metameric spectrum of same substance, and special stony land. According to the classification standard of National Environmental Protection Bureau in 2000 and actual situation in Huajiang karst gorge, the author adopts the technique wh...

根据国家环保局2000年分类标准，结合花江喀斯特峡谷的实际情况，本文采用了RS、GIS和传统勾绘技术相结合的方法进行土地利用类型划分，分类结果表明此方法是可行的，其精度可达89.65%。

The research on landuse change and agricultural investments is systemic, general, macroscopic, descriptive and monistic.

国内外对于土地利用变化和农业投入的研究具有系统性、概括性、宏观性、描述性、单一性的特点。

Soil erosion intensity presented the characteristics of nubby discontinuous distribution in spatial, which is

采用影响度指数表示评价单元的土壤侵蚀对水质的影响程度，选择土地利用、离沟道距离、K值、坡度和侵蚀模数等作为评价影响度的影响因子，采用专家打分和综合评判法并结合GIS对土壤允许流失量进行判定；研究表明，研究区土壤允许流失量在100～500 t/km~2·a之间，且以200 t/km~2·a占绝大多数，100 t/km~2·a、300 t/km~2·a、400 t/km~2·a和500 t/km~2·a仅有零星的分布。

Secondly, the dry land from landuse database was overlain with slope database, soil erosion database, normalization vegetation index database.
