Planning and Design of Urban Riverfront Spaces Based on Comprehensive River Regulation:A Case Study of Comprehensive Regulation Project of the Old Huan River in Hubei

Urban construction in China has changed from“extensional sprawl”to“connotative development”.With the accelerating urbanization and improvement of living standards,citizens have had higher and more requirements on urban waterfront spaces.Starting from the history and characteristics of comprehensive river regulation,this paper explored its multiple meanings against the new appeals of urban development.On this basis,design and planning approaches were discussed from 3 perspectives of waterfront space planning control,waterfront space design optimization,and improvement of waterfront landscape,then the planning and design strategies of urban waterfront spaces were explored by studying the comprehensive waterfront space regulation project of the Old Huan River in Hubei,so as to provide references for the comprehensive water system regulation and space planning and construction of urban waterfront spaces.

A Review of Comprehensive River Regulation Specification

Comprehensive river regulation in the new era is a series of construction procedures from planning,scheme generation and engineering design to commercial pattern,construction and operation,etc.,which is a comprehensive project coordinated and managed by multiple departments.Different industry departments measure the feasibility of scheme design according to the standards of their own departments in the examination of river regulation,but due to the lack of understanding of other industry standards,some unnecessary scheme contradictions are often caused in the cross-industry cooperation.The study integrates and sorts out specifi cations of various departments involved in river regulation,and performs analogy study of standards of various contents in multi-industry cooperation with contents of comprehensive river regulation as the scale,so as to promote cross-industry communication of comprehensive river regulation and promote construction of integrated river regulation platform.

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.
