Abstract


Hebei Province, a serious lack of water resources, the contradiction between supply and demand of water resources has become increasingly acute, and the issue of water resources has increasingly become a regional sustainable development \Conventional water resources, including surface water and groundwater resources only as an important part of the water resources, soil development and utilization of water resources is receiving attention. Hebei Province, rich soil water development and utilization of soil water is the source of all terrestrial plant moisture absorption and is essential for crop production conditions. In case of a severe shortage of water resource in an important way, scientific, rational and efficient use of soil water resources is of great strategic significance, but also to solve the water crisis in Hebei. Carrying Capacity of soil water resources development and utilization of the premise, the concept of water resources carrying capacity based on soil water and soil, considering the various factors affecting soil water carrying capacity, calculated to facilitate the evaluation of soil water resources carrying capacity. The main content of this paper is as follows: 1. Outlines the significance of the study of soil water resources carrying capacity the partition profile at home and abroad on the progress of the bearing capacity of the soil water resources and soil water resources in Hebei Province, as well as to determine the content. Write out the meaning of soil water carrying capacity and write characteristics of soil water carrying capacity, according to the characteristics of the water resources carrying capacity. Depending on the circumstances, write the influencing factors of soil water carrying capacity, soil water carrying capacity evaluation index system and write according to these factors. Begin with a common evaluation and calculation methods to pick out the most suitable for this article Evaluation fuzzy comprehensive evaluation method based on the advantages and disadvantages of these methods. Then fine fuzzy comprehensive evaluation method evaluation of soil water resources bearing capacity of the Taihang piedmont plain area, and calculate the block diagram of the fuzzy comprehensive evaluation method is given. 4 out the details of the evaluation method based on fuzzy comprehensive evaluation of soil water resources bearing capacity of the Taihang piedmont plain area, according to the different frequencies, respectively Taihang piedmont plain bearing capacity of soil water resources evaluation, analysis, and evaluation results . 5. Comprehensive analysis of the results of the evaluation of the fourth chapter, the proposed measures on the improvement of the soil water carrying capacity of the Taihang piedmont plain area. Finally chapter conclusions and recommendations. This article summarizes the research on the application of fuzzy comprehensive evaluation method of the lack of soil water resources carrying capacity assessment. The conclusion of this article: the fuzzy comprehensive evaluation method to evaluate the bearing capacity of soil water resources of Taihang piedmont plain area to obtain a satisfactory evaluation results in different frequency years. As a result, there is conducive to the further study of the bearing capacity of the soil water resources in Hebei Province. The purpose of this study is to objective analysis to evaluate the Taihang piedmont plain area of ??soil water resources carrying capacity in-depth study, the efficient use of water resources, water conservation provided before the prerequisite for the calculation of the bearing capacity of soil water resources in Hebei Province.
