Study on the integrated process analysis system of runoff regulation and control technology and strategy of slope farmland

Following the appearance of regional unusual water resources problems under the background of global climatic change, such as topical and incontinuous water shortage in the southern of China, so, it is very useful to make research on regulation and control of slope farmland runoff (RC-SFR) in the region of southern China (RSC). For finding the current status and major problems of SFR, the typical watershed in RSC is selected to make field investigation. Then, based on the present technologies and methods of runoff regulation, the integrated process analysis system of runoff regulation and control technology and strategy (IPASRRCTS) is originally developed, which includes requirement estimate, potential analysis, benefit evaluation. In addition, it also includes specific designation and distribution of RRCTS. According to the attributes and characteristics of RRCTS, IPASRRCTS could be divided into analysis and evaluation system of runoff regulation (AES-RR), project and technology system of runoff regulation (PTS-RR), application and management system of runoff regulation (AMS-RR). Followed the appearance of IPAS-RRCTS, it has certain advancing significance to the development of runoff regulation theory and method. At mean time, the analysis step of IPAS-RRCTS is forwarded in this study, which could offer scientific supports for effective application and demonstration of RRC in other regions.
