Research Of Carrying Capacity Of Water Resources Of Jilin Province

Water resources are the most valuable resource on which human survival and development, there is no substitute for it, and it's the significant factors in human survival and social development. The shortage of water resources is the major problems in the 21st century to all humanity, and the water crisis is developing very fast, how to seek a feasible and effective solution is becoming a common thorny problem of mankind. The researching of Carrying Capacity of Water Resources has now been put on the agenda.Carrying Capacity of Water Resources which is called a region of water, In the stage of social development and technology development, except as destroy the social and ecosystem, carrying the maximum of the social scale economy Development, it's one of the combine target is developing as social, economy and technology change. As Carrying Capacity of Water Resources want to say the content, we compare calculations the different area Carrying Capacity of Water Resources and we get some different numbers of the Carrying Capacity of Water Resources.Carrying Capacity of Water Resources highlights the value between the water resources and economic and social development, embodies the development relationship between the population, economy and the resources, and it's an important factor for the sustainable development of an area. This paper is basic on classifying the Jilin Province, by study and analysis the water resources carrying load index, water resources carrying capacity and water resources bearing capacity factor in 2003-2007 , coordinate the relationship between ecosystem, people's living conditions, the development of modern agriculture and industry and the water resources, in order to realize sustainable use of regional water resources, ensure national economic and social development, improve the living standards.At the present time, our country Carrying Capacity of Resources based on the principle of Carrying Capacity of land Resources research and Carrying Capacity of economy resources, there are less for the Carrying Capacity of water Resources, compare with Jilin province there are much less for the Carrying Capacity of water Resources. This text use the up to date annual statistics data and purchase the water resource data from the Jilin hydrology water resource bureau database, at last find out the research conclusion.This paper studies based on the idea of sustainable development, using the latest development of State Family Planning Commission, planning and research methods of functional, water resources carrying capacity evaluation method, including water resource based evaluation and analysis, based on the balance between supply and demand of water resources development and utilization of load system based on population and the potential evaluation and the relationship between the water resources carrying capacity of water content such as evaluation, evaluation and analysis on through the review all region can be divided into water, water balance overloaded area, water surplus. Select the water resources carrying capacity of water resources, water index, index system load index three. The author calculated separately in Jilin province regional water resources carrying capacity of Jilin province, which is a region in the problems of the water resources carrying capacity, and gives corresponding solutions.The full text has five main sections. Section one is the theoretical principle of research, include the definition of water resource, water resources of carrying capacity index, carrying Capacity of Water Resources, Water Resources Carrying index etc. Summarize the current situation of research of the Carrying Capacity of Water Resources. Section two, to introduce the research method, model and data, also show the computing formula of the Carrying Capacity of Water Resources. Section three, to introduce the current situation and feature. Section four, separate calculate the water resources of carrying capacity index, Carrying Capacity of Water Resources, Water Resources Carrying index of Jilin province, according to the evaluate method classification the data and contrastive analysis Jilin province area. Section five, include suggestion and conclusion.The calculation results show that the area within the province, the load index of water resources in Changchun is more than 10, the water resources carrying capacity is less than actual population, according to the water resources carrying capacity of water resources evaluation index is balance, the water resources carrying capacity is a critical overload condition; In Siping, Liaoyuan, water load index is higher than 10, the water resources carrying capacity is greater than the actual population, according to the water resources carrying capacity of water resources evaluation index is balance or the water surplus, the water resources carrying capacity is a critical overload condition. rich overloaded Songyuan and Baicheng region water load bearing capacity, water is higher than 10 index than actual population, according to the water resources carrying capacity of water resources evaluation index of water resources and water balance is type, the water resources carrying capacity overloading region in critical condition or state; overloaded Jilin area water load index between 5 ~ 10 between regions, the water resources carrying capacity is greater than the actual population, according to the water resources carrying capacity of water resources evaluation index for the water resources carrying capacity, water surplus in rich; state Tonghua, Yanbian water load index between 2 ~ 5 between regions, the water resources carrying capacity far outweigh the actual population, according to the water resources carrying capacity of water resources evaluation index of water surplus, belongs to the water resources carrying capacity status in affluent or more than state, Baishan water load index between 1 ~ 2, the water resources carrying capacity far outweigh the actual population, according to the water resources carrying capacity of water resources evaluation index of water surplus, belongs to the water resources carrying capacity is more than the situation.Research of the Carrying Capacity of Water Resources, for Jilin province economy, population and the relationship between man and nature, and promote the harmonious, thus eventually realize the sustainable development of economy and society has important theoretical and practical significance. How in the water under the condition of limited, and promote the sustainable development of society and economy is facing the problem of Jilin province will. Relevant decision-making departments in formulating economic development targets, must be the factors into consideration, the water of Jilin province that population, resources, economic and social sustainable development.
