Research On Cross-section Of The Multi-purpose River In The Area Of River Network

The water is the important resource for survival and the development of humanity, also is the controllability essential factor of ecological and environment. The river-renovated play an important role in hydraulic engineering. The people through the measures of govern lead, scour, protection of river bank and so on to carries on the government and the control to the rivers, for the aims of eliminating the trouble and populating the advantage, carrying on drainaging flood, taking water and make use of it, and transportation and shipping. Along with human society's development, the humanity doesn't request to merely limit to the river these basic functions, but also has contained the ecology and the landscape. This article unifies the Wenling city example, discussed cross-section of the multi-purpose river design and the appraisal method. The paper's main content including following several aspects:1. Summarized the river cross-section designed methods under the sole function, has provided the rationale for the multi-purpose river cross-section design.2.Through summarizing and analyzing the functions between mutual conflict, from five aspects that is the engineering material characteristic, the ecology landscape function, the society affects, the economy, and the environmental effect, established the cross-section of multi-purpose river appraisal target system, which is composed by the aims level, the criterions level, the targets level, and the plans level. Has made use of the fuzzy uniform matrix, the analytic hierarchy process to carry on the appraisal on it.3.Has carried on optimal using the appraisal system to Wenling's river cross-section plan.
