Due to rapid growth of population, urbanization and industrialization, in many cites of the developing world, there is severe contradiction between urban land supply and land demand which resulted in many urban land use conflicting situations and urban environment degrading. This paper is mainly focused on this problem, demonstrating the feasibility and efficiency of environmental study by integrating GIS and environmetal zoning method. Two neighbourhoods of the old city of Wenzhou were chosen as the study area. With the aid of GIS software PC Arc/info as dBate IV, an urhan environmental impact assessment study was carried out based on the data available such as land use map and detailed attribute data of each land planning unit. The main factors taken into consideration include: the type of activity causing environmental stress, the type and strength of environmental impact and the type of receptive area that could be affected.

The major project 'Researches on the environmental changes of the Yellow River Basin and laws of water and sediment transponaion' wasmanaged jointly by the institute of geography of Chinese Academy of Sciences(cas) and State Planning Commission with the Yellow River ConservancyCommission of Ministry of Water Conservancy of China covering the period of July, 1988-December, 1992. All of the anticipated objectives of the project had been completely reached, and research results of the project were checkedand accepted in July, 1993 in Beijing. The project is charactenzed by thecomprehensiveness in research with systematic and all-around conent throughclosely combining environmotal changes with water and sedimenttransportation in the Yellow River basin, and giving full play to the superiority of the cooperation of multiple disciplines and units.A series of major problemswere well replied in the end. Besides studying some problems of the moment,some basic researches on the prosped of reducing sediments delivered into theYellow River after 2000, the ways to prolonging the lifetime of the current lowerYellow River channel, the program of comprehensive management and development of the drainage basin, etc., were carried out. Moreover, the projecthas outstanding features comparing with other researches on the large rivers inChina, and is uncommon in the field of researches on rivers all over the world.

Starting from the supposition of time-space substitution, the Langbein-Schumm's Law was applied to deal with response of fluvial erosion System to the changes in mean annual Precipitation induced by global green-house warming. As a result, a simple method was put forward to predict change in sediment yield, with Ningxia Hui Autonomous Region in the northern fringe of the Loess Plateau of China as an example. Results show that, even the change in mean annual precipitation is the same, the direction and magnitude of the resultant chang in sediment yteld would be quite different in fferent physico-geographical zones. When mean annual precipitation is increased, sediment yield in arid or semi-arid areas with a mean anntal Peripitation of less than 400 mm will be increased, while sediment yield in sub-humid or humid areas with a mean annual precipitation of more than 400 mm will be ***, the complex response of fluvial erosion system in time series due to the lag of change in vegetation behind the changn in precipitation has also been qualitatively discussed in this paper.

From the angle of regional development, this article gives a brief account of the natural conditions, socio-economic development, the calamitous environment of the Huaihe River, the achievements and existing issues in the harnessing of the River since the founding of the People’s Republic. In addition, it suggests some harnessing tasks set for the on-going Ninth Five-year Plan and some problems to be dealt with prudently.

Northern Shaanxi is located on the Erdos syncline, a subdivision of North China Shield. The loess landforms are the main landform types, additionally, there are low rocky mountains and hills, valleys and eolian landforms. Changes of techonic bases and of water-heat conditions in the region cause obvious regional differentiations of the landcape. From south to north,accompanying with uprising of the relief and decrease of mean annual temperature and precipitation, the types of landforms, degree of dissection,vegetation cover-degree and intensity of soil and water loesses show clearly latitudinal zonation.

A multi-constituent water quality model is presented,Which relates carbonaceous biochemical oxygen demand (CBOD),amonia (NH3-N), nitrite(NO2-N), nitrate(NO3-N) and dissolvedoxygen(DO). The parameters are solved by Marquardt Method (i. e.,Dampled Least Square Method) while initial values inoptimization are produced by Monte-Carlo Method. The Potential ofthe method as a parameter estimation aid is demonstrated for theapplication to the Liangyi Rver, JiangSu Province of China and by aspecial comparison with Gauss Method.
