Due to an abundant rainfall and frequent rainstorm, and geographical characteristics of mountain and hills, the potential erosive dynamics of soil erosion is strong. The low resistant erosion ability of ground substance, especially in granite weathering crust and purple rock and its soil are the inner causes of severe soil erosion. The utilization of natural resource of mankind was increased due to characteristics of social and economic environment of the province. The unreasonable land utilization caused vegetation destroy, which is the key factor of soil erosion.

丰沛的降雨和频繁的暴雨，以及多山地丘陵的地形特征，为土壤侵蚀提供了强大的侵蚀潜在动力；抗侵蚀性较弱的地面组成物质，特别是花岗岩和紫色岩风化壳及其土壤，是造成土壤侵蚀特别严重的内在原因；而社会经济环境特点使人类利用自然资源强度增加，出现了一系列土地利用不合理现象，导致其中植被破坏，是造成土壤侵蚀的决定性因子。

Based on ETM(superscript +) remote sensing data of American Landsat-7, PCI V7.0 software was applied to process series of remote sensing data, including band ratio 4/3 and principal components 1, 3, 4, 5 hands. These objects classification information was extracted and the land use situations in Kunming were studied by using the composed image method of principal components and ratio.

以美国Landsat-7陆地卫星ETM遥感影像数据为信息源，利用遥感图像处理软件PCI V7.0进行波段4/3比值增强处理和波段1、3、4、5主成分分析，采用主组分加比值合成影像图的方法，即ETM4/3+PC3+PC1，提取各类地物分类信息，研究昆明地区土地利用情况。

In 2003,on the whole the soils in Wujiang were little acid, pH from 6.40±0.38 to 5.40±0.55now, and the trend of acid was in Tailake region. The available phosphorous in Paddyfield were significantly lower than. the other five land use patterns. As a result,controlling the phosphorous output form vegetable field mulberry yard and other dryland might be more significant to control the non-point pollution in Tailake region.

吴江市土壤基本上属微酸性土壤，2003年耕地监测中土壤pH值由1982年的6.40+0.38变为5.40±0.55，可见近20年来太湖地区普遍存在的酸化趋势；在稻田、林地、桑园、菜地、果园、旱地六种常见的土地利用方式中，稻田土壤速效磷显著低于其它五种利用方式中；因此，在控制太湖地区磷的面源污染上，控制菜地、桑园和其它旱地土壤磷的输出可能更为迫切。

By using the TM images in 1997,2001 and the spatial analysis methods of remote sensing and investigated by quadrat,the dynamic change of vegetation,land use and soil erosion in the "Shan-Gan-Ning air mass to Yinchuan" natural gas pipeline project region during the period from 1997 to 2001 are analyzed.

基于在中国西北生态脆弱区天然气管线建设的工程实例，利用夏季陆地卫星图像为基本信息源，应用遥感解译分析、野外样方调查等方法，以植被类型、土地利用、土壤侵蚀为基本评价因子，对天然气管线建设前、后项目区的生态环境变化进行了分析研究。

Based on field investigation and historical data analyzing, the characteristics and causes of flood disasters of Qinba Mountain area were discussed in this paper. Take the harnessed Watershed and unharnessed Watershed as comparative study objects, through analzing the two typical watershed land using and rainfall-runoff dynamic data, combinating the in-situ soil infiltration field testing, a rainfall-runoff model of small watershed which was appropriate to Qinba Mountain areas was built based on improving the SCS model. And then the influence of soil and water conservation measures on the flood processes was analysed.

本文通过野外调查与历史调查资料，阐述了秦巴山地区洪水灾害的特点及成因，以治理流域与未治理流域为对比研究对象，通过对两条典型流域的土地利用状况分析，结合土壤入渗原位测试，充分利用降雨、径流动态观测资料，以SCS模型模拟降雨径流为重点，建立适合于秦巴山地区小流域的降雨径流计算模型，分析水土保持措施对于洪水的作用过程。

This research utilizes MUSIC（the Model for Urban Stormwater Improvement Conceptualisation）in Yong-Ann watershed to divide into three kinds of land utilizing type attitudes, it is the forest land, farmland and residential area respectively, and three kinds of structural BMPs facilities, it is the grassed swales, vegetated buffer strips and detention basins respectively.

中文摘要本研究利用MUSIC（the Model for Urban Stormwater Improvement Conceptualisation）将永安集水区划分为三种土地利用型态，分别为林地、农地及住宅区，以及三种结构性BMPs设施，分别为草沟、草带及滞留池。

The impacts of intensity of agriculture activities, landuse change and irrigation system change upon underground water were analyzed based on more than 20 years' hydrochemical data.
