On Some Theories And Means Of Comprehensive Reclamation Urban Rivers & Ecological Construction

A river serves as a most essential resource either when a city begins to take shape or when it already starts developing. A river also embodies its general environment. The existence or non-existence of a whole city rests largely upon the river which can have a great influence on its own development and affect its stylistic characteristics as much as its beautification. China presently is not doing a quite satisfactory job, though the utility of urban rivers(UR) has highly expanded and enriched, along with the evolution of society, the development of scientific technology, ever-speeding urbanization as well as the elevation of public demand. Although greater attention have been paid to water environment construction, tourism exploitation, ecology conservation and water culture cultivation since the late 1990s, and some preliminary practice have also been carried out, there's a lack of comprehensive study and analysis of the basic principles, specific methods and programmes of Comprehensive Reclamation of Urban Rivers and Ecological Construction(CRUREC). As our country is still at a stage where we are valuing natural resource exploitation against environment protection, theoretical guidance and practical experience are essential to keep us on the right track trying to administrater urban rivers well and to maintain a sound ecology. Therefore, this thesis primarily aims at discussing some basic theories, principles and some programmes about CRUREC, to bring new elegance to modern cities to inspire better ideas in others.Based on a synthesis and induction of the research conducted on some cutting-edge scientific areas concerning CRUREC both in and abroad, after certain case study of CRUR(Comprehensive Reclamation of Urban River), according to practical experiments carried out on the Baoji urban areas of Weihe River, abiding by all the basic principles of landscape ecology, ecology restoration, ecology engineering, tourism & tourism psychology, sustainable development and trilism of landscape planning and design. The thesis has generally come to five major principles, which respectively refer to first, humanitarian CRUREC so as to achieve a harmonious co-existence of man and nature; second, treatment on both specific cases and the essential causes to put a check on pollution so that its capacity of self-purification can be restored and strengthened; third, employment of ecology engineering programmes to make rivers become natural and hygenic; forth, city beautification and expansion of urban river utility, and at last, sustainable development. Meanwhile, put...
