Study On Regional Industrial Production's Spatial Distribution And Water Pollution Control

With fast economic growth, industrial water pollution has been a serious problem ubiquitously in China. More threatening is that lots of economic developing regions still strategically depend on fast industrialization, neglecting the relationship between production's spatial distribution and regional water environmental carrying capacity. As a small region, Liuzhou City is the objective case.To research regional industrial production's spatial distribution and water pollution control of Liuzhou. This study at first presents an expert system called WPC-ES (ES), which can analyze relationships between industrial water pollution and economic activities of industrial enterprises of a city. The system includes a decision model as its core, which integrates another four closely related subsystems. This system was used to estimate the pressure of water pollution control of Liuzhou City in future, results of which quantitatively showed that the pressure of water pollution control has a increasing trend in next 5 years. And then, this paper propose a plant-level aggregation method to estimate the spatial distribution of industrial productions and its water pollution pressure of Liuzhou in the future five years. Based on discrete event simulation, newly added industrial projects' sizes, location choices (refer to industrial location theory), and production values are regionally aggregated. COD (Chemical Oxygen Demand) emission into every river reach in the region is calculated respectively. In order to recover the water environmental function, the strategy aims at controlling emission within the carrying capacity of each river reach. The results include the spatial distribution of industrial production values and water pollutions' load in Liuzhou City, and the diversified uncertain bounds of river reaches' COD adoptions, which will aggravate the water pollution.The resultes of this paper can assist Liuzhou's decision maker to support their strategies, which can ensure the rationality and sustainment of Liuzhou's development. In addition, based on the prediction of industry spatial distribution of Liuzhou City, the paper in the end proposed some strategies to strengthening Liuzhou's industrial cluster, which aim to improve the rationality of the spatial distribution of local industry, and to make its industrial clusters and industrial spatial distribution more competitive.
