The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.

研究结果如下：首先针对荒漠化地区的地物特征，对高光谱数据不同波段的数据质量、波段组合进行了评价，提出了适用于荒漠化监测的基本波段选择集；初步了解和掌握了研究地区的地物光谱特性及变异规律，进一步明确了掌握地物光谱特征和变异规律是用成像光谱仪数据提取地物信息的基础；发现了基于光谱整体形状的分类方法在很大程度上能够消除由于传感器、地物目标观测方向之间的角度变化引起的反射率曲线整体平移的"同物异谱"现象，对于谱形相似而整体反射率的值相差较大的两类地物，通过引入均值和方差图像参与分类得到解决；研究还表明在植被"红边"范围内的波段是进行荒漠化监测的主要特征波段，这些波段与植被生物量和盖度都有密切的关系，是开展精细植被分类研究和植被定量反演的重要基础；像元的导数光谱分析可以消除土壤背景的影响，是进行植被生物量和盖度定量反演的有力工具；建立了荒漠化监测主要评价因子的定量反演模型，并分析了模型的适用性。

The Forest fire prevention is the technology which has much relations with geographic information, so if we make use of 3S technology, we can greatly improve the levels in the area of monitoring, saving, forecast, analyze, statistic and decision so as to prevent in unfired state and discover at litter fire and save life and properties in time. Only by this way can we reduce the losses from forest fire disaster and protect the forest ecological resources and pepoles life and properties.

Because tourism products are intangible, perishable and untransferable and purchase behavior of tourists is flexible, tourism destinations and tourism enterprises have to convey all the information of destinations or scenic area to each tourist. Therefore, destinations and tourism enterprises consider commercials or ads in all kinds mass medias and tourism trade shows as the major means of promotion.

旅游产品的无形性、不可存储性、不可转移性及旅游者购买旅游产品的伸缩性使得各旅游目的地或旅游企业必须向消费者传递每一个旅游目的地或旅游景区的信息，这样以广告形式在各类媒体或旅游推广会上宣传自己就成了各旅游目的地或旅游企业的一个最重要的促销手段。

The research is about the reuse of urban sewage for virescence irrigation, and the influence of sewage irrigation on eco-environment such as soil, plant, etc. is studied. Under the condition of field sewage irrigation, the transport and transformation and accumulation mechanism of heavy metals, nutrients and organic pollutants as vaporizable hydroxybenzene etc. in the soil-plant system are analyzed. The heavy metal pollution is evaluated by the comprehensive pollution index. The spatial variability of heavy metals in sewage irrigation area is further understood. The spatial variability of heavy metals and physical and chemical properties of soil are reflected in a more straight way by the theory model of variance function curve based on the geographical information system.
