On the basis of comprehensive analysis on present achievements of water reduction by artificial afforestation and environment conservation regionalization of upper and middle reaches in Yellow River,water reduction norms of artificial.

Annual runoff amount of river basin is a significant basis of water resources evaluation and its allocation in reason, while water reduction norm of soil conservation is a foundation of estimating influences of soil and water conservation on annual runoff amount of river.

Probe into the municipal water and public water consumption quota in Jiangsu Province;

Connecting with the practice of energy management work, this paper expounds the method of and existing problems in determining water consumption quota in production of diaphragmatic alkali.

Based on analysis and consideration of the main factors influencing industrial and municipal water consumption quota, this paper develops the data analysis system of the industrial and municipal water consumption quota that makes the formulation of water consumption quota be simplified and be weighted with unified standard.

This system has many functions,including data edit,water data and spatial data query,several methods of statistics and analysis,water quota model,water demand mode.

The importance of water quota in water resources management and its development process are presented.

This paper analyses the water quota for agriculture irrigation and water saving potential in Xinjiang, and provides the science basis for controlling water supply, based on the factual state of water supply to agriculture irrigation and other businesses.

The model was divided into 4 contents:prediction of gross economic amount,prediction of economic structure,prediction of water demand quota and prediction of wa.
