Research On Regional Water Resources Development And Carrying Capacity

Water resources is one of fundamental natural resources and controlling factors of ecological environment, and in the meanwhile, an organic part of overall strength of the country and strategic economy resources. Looking forward to the future, water resources gently affects environment and development of the globle. In the historical reference, the people of our country have been struggling with frequent flood and drought. Since New China established, we have made large-scale water conservancy construction, and taken out a significant success.Our country ,which owns 22 % population of the globe,but 6% renenable water resources and 9% plough land of the globe, sustains dining problem and economic advance. But, in the course of the water resources development and utilization , there is more complicated new situation and problem. Large flood in Changjiang River and Nenjiang River in 1998, Yellow River cutting off its water supply since 1990 , increasingly serious sandstorm and water pollution in the north arouse the attention of the whole people or rather the world.The study on development , utilization and bearing capacity of regional water resources is a coordinational development problem of sophisticated system. It not only involves technological problem, but also economic, social and policy problem. How to carry out quantitative study, especially not technological aspect , is quite extrusive problem nowadays in the hydrology and water resources domain.This paper sums up domestic correlative research findings, and carries out the study of the water resources development , utilization and bearing capacity on account of sustainable development perspective and the basic concepts of the water resources development , utilization and bearing capacity . Main contents of the research includes: on the basis of system theory and sustainable development theory, in terms of exploring quantity ,quality , regularities of distribution of regional water resources, present situation of water resources development and utilization, and social economy, studys the relation between economy development and ecological environment water requirement, explore protection object and reasonable water requirement of regional ecology environment, raises matching water resources reasonable dispose scheme of enconomy development and ecology environment protection, analyzes water resources bearing capacity, and offers scientific decision-making reference of regional economy develop. Finally, it synthetically applies the theory, model and method of the water resources development , utilization and bearing capacity study mode, carries out deep study and analysis on the problem of the water resources development , utilization and bearing capacity in Jiangmen City, and obtains many valuable results.
