The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the "M" type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives.展开更多

Despite that there is a considerable amount of scientific researches on the urban nature in urban and suburb area, the comprehensive research of URNA is still rare. After analyzing the concept and value of URNA, this paper presented a methodology for comprehensive evaluation of URNA by adopting methods of document analysis, prior-selection process, analytic hierarchy process and vector resemblance-degree. As a result, the comprehensive evaluation index of URNA includes target level A, rule level B(ecological environment value, ecological recreation value, social culture value, scientific research value), index level C( diversity,singularity,nature,area,stability,recreation,landscape element,aesthetics,history,scientific), and index level D(20 items). Each index weight of comprehensive evaluation system of URNA of Shanghai was confirmed finally.展开更多
