Karst in shanxi province is representative of that in northern {2., and karst water systems discharge in the form of springs that are among the most important sources for local water supply. Since the 1950s, attenuation has been the major trend of discharge variation of most karst springs at shanxi. Based on the case study of 7 karst springs including Niangziguan, Xin’an, Guozhuang, Shentou, Jinci, Lancun, and Hongshan springs, the discharge variation process of karst springs was divided into natural fluctuation phase and anthropogenic impact phase. Discharge attenuation of the 7 karst springs was controlled mainly by climate and human activities, with their contributions being respectively about 60% and 40%. According to the dif-ference of the effect of climate and human activities for each spring, attenuation modes of spring discharge fall into three types: natural process dominated attenuation type, exploitation induced process dominated attenuation type, and mixed attenuation type. The total restored discharge variation of 7 karst springs matched well with the global air temperature change in 1956―2.00, clearly indicating the trend of global warming and aridity in the last several decades, and the analysis of discharge variation processes of karst springs can be used as a new tool for global change studies.

E-commerce is the execution of business transactio ns over the Internet. Companies conducting e-commerce can perform most of the tra nsactions which they are doing now. Most of the marketing method should coincide nt with the changes in e-commerce world. Brand ability will be depressed, but corporate identity and brand identity will be upgraded. So the enterprise should lower the cost of distribution, manufactur ing, and supplying. We can also upgrade the product value which consumer con ceded. Logistic will be core ability. The 3pl and 4pl will be used more and more often. The importance of transportation has grown with the increasing globalization as well as the growth in e-commerce. Firms should identify various transportation network design options and their relative strengths and weaknesses. They should also use methodologies for routing and scheduling deliveries in transportation network. The savings matrix and the generalized assignment methodology can be us ed to minimize the transportation cost while meeting delivery commitments to cus tomers. Information is essential to making good decisions. Information technology provid es the tools to gather information and analyze it in order to make the best deci sions. Information plays a key in every company. Information technology will be used broadly. It is a factual component on which decisions about each of the transportation, facilities, and inventory. In essence, information is the glue that holds the company to other firms, and allows it to function, making informa tion the most important firms drivers. Custom relation management, data based marketing, one to one marketing, electron ic odder system, electronic data exchange, will be used frequent. These new mark eting method is using information technology all. IT investment in program will greatly increase. The consumer can find and compare the price in every character easily on Interne t. Cost becomes the most important factor in product selecting. So the e

This paper established sustainable land resources evaluating indicators fit for hilly area in Sichuan Basin, Southwest of china, and evaluated the case of sustainable land {2. of Lezhi County from 1990 to 2.01. The result showed that the land resource sustainable utilization ability in Lezhi County is belong to Second level （better sustainable）. Secondly, this paper diagnosed some years obstacles of sustainable land {2. of Lezhi County from base period to goal period and compared the obstacles factors in the indicators system. There were 16 indexes orderly become major affect factor to land sustainable utilization of Lezhi county in indicator system, of which there are 8 obstacles indexes exist both in 1990 and 2.01. The value of obstacles degree of five indicators exceeded 5 in 1990, but in 2.01, only two indicators＇ values were more than 5.

The thermal-mineral waters in Siping'an district are hydrogeologically and geochemically unique in *** occurrence is controlled by faulted structures in Precambrian *** physico-chemical properties, hydrochemical thpes ,major and minor elements ,dissolved gases and organic suboances have been characterized to describe the hydrochemical features and therapeutic effect of the thermal-mineral waters. Hydrogen, oxygen, sulfur and helium isotope compositions of the waters were measured tO explain their ages, origlm and related geochemical procee. The thermal-mineral waters have been formed as a result of the deep circulation of meteoric water in fractures and fissures of hard rocks. Miking of the thermal waters from the deep with cold groundwaters in the Quaternary sediments and the Hutuo River water takes place when the thermal waters move upward to the discharge area.

This article brings forward a design and realization scheme of Web GIS in the Yellow River basin for the management of groundwater {2.s. The main goals are to manage and share data of massive-scale, to support the research of groundwater {2.s in the Yellow River basin. In this paper we point out the necessity and feasibility of building the distributed Web GIS for geographical research objects on a large scale. We put forward some solutions for the construction of this kind of system including a holistic deployment strategy in the Internet, a scheme of distributed data storage and management, a design of application structure based on three tires architecture by each province and how they collaborate with each other. It also illuminates how the application server works, and sets forth the relations among databases which work together in this system.

By means of ISM (Interpretative Structural Modeling) and SD (System Dynamics) methods, this paper made a system dynamics model of urbanization and eco-environment coupling in Jiangsu province according to the implication and PSR (Pressure State Response) framework of urbanization and eco-environment coupling. Moreover, five typical scenarios during 2.00-2.15 have been simulated and analyzed based on the time serial statistical data during 1990-2.03 in Jiangsu, which indicates: firstly, there are significant differences between the results and the scenarios, and the five coupling models all have comparative advantages and drawbacks; secondly, in terms of the characteristics and regional development disparities of Jiangsu and the general rule of world urbanization process, this paper reveals that only when either population urbanization model or social urbanization model to be correspondingly adopted, the sustainable development among population, economy, urbanization and eco-environment can be realized.

The typical style and features of mountains and waters in Caoshi Ancient Town,have hitherto been well preserved. Caoshi Ancient Town boasts superior base of the natural eco-environment and deep-rooted background of regional culture,where mountains,waters,shoals,towns and other landscape elements are merged harmoniously,the transportation and geographical conditions have been fundamentally changed. Ancient towns,old temples,ancient forests,ancient wells and ancient piers are unique in different ways,with characteristics of tourism {2.s such as long history and ancient folklore. It should seize the historical opportunity of china vigorously developing rural tourism based on the construction of the new socialist countryside,to make characteristic agricultural economy gain ground; assume the leading role to drive the development of tourism economy in surrounding areas; correctly handle the relationship between development and protection to walk the path of sustainable development of tourism.
