ANALYSIS AND CALCULATION OF REGULATED WATER RESOURCES OF GROUNDWATER RESERVOIR

Groundwater reservoir is a kind of important engineering, which can optimize water resources arran- gement by means of artificial regulation. Regulated water is the blood and value performance of groundwater reservoir. To resolve the problem of real-time quantification of regulated water, the paper analyzed sources and compositions of regulated water in detail. Then, under the conditions of satisfying water demand inside research area, the paper analyzed quantity available and regulation coefficient of different regulated water and established a formula to calculate regulated water. At last, based on a pore groundwater reservoir in the middle reaches of the Yinma River, Jilin Province, the paper calculated regulated water with the formula and the result shows that the method is feasible. With some constraint conditions, the formula can be adopted in other similar areas.

Study on ecological and economic effects of land and water resources allocation in Sanjiang Plain

The pattern of groundwater usage and industrial development in the Sanjiang Plain remains a concern of Chinese government. In accordance with the Water Conservancy Planning of the Sanjiang Plain, this paper presents a Sanjiang Plain resources allocation model which is established to be used in controlling water, land, ecology and economy in consideration of 50%-level and 75%-level years, planting structure adjustment, industry development by 2020, and different transit water exploitation schemes. Lingo10 global optimization has been adopted in solving the model. The results show that by 2020 the output of three industries will increase to a certain degree, the grain yields will satisfy state demand, and regional service value will decrease dramatically. Such results provide theoretical basis and practical significance for instructing the development and exploitation of the Sanjiang Plain.

Validity Checks for Natural Resource Regulation on Regional Economic Growth in China on the Basis of Provincial Panel Data

We analyze the mechanism of natural resource regulation on regional economic growth and estimate the model based on panel data for 31 Chinese provinces from 2000 to 2009. Our findings suggest that a fixed effect model is more appropriate than a mixed cross section or random effect model. A fixed effect model between natural resource regulation and regional economic growth quantity and quality was constructed to check the validity of natural resource regulation on regional economic growth. We found that natural resource regulation is effective at regulating regional economic growth; and natural resource regulation restrains regional economic speed to some extent. The per unit growth of natural resource regulation intensity will cut 24.6 billion CNY in gross domestic product; however, natural resource regulation can improve the quality of regional economic growth. Growth in the per unit natural resource regulation intensity will increase the index of regional economic growth quality by 0.022 units. In summary, these data support the proposal for using natural resources to regulate regional economic growth and transformation.
