Urban green space system is a key region for protecting ecological resources. Taking Chongqing Economic and Technological Development Zone as an example, on the basis of in-depth survey, it made a systematic study on green space system planning combining current situa- tions of green space and regional spatial characteristics of Chongqing Economic and Technological Development Zone. It discussed how to restore and build urban green space system, protect ecological environment, and promote regional economic de- velopment and harmony between human and nature through design of ecological technologies and landscape in the ecological planning of urban green space system.展开更多

Five typical places in Mount Lushan with the ideal landscape characteristics like the East Grove Temple, White Deer Cave Academy, Simplicity and Tranquility Monastery, Lushan Valley, and Villa-cluster of the East Valley were analyzed, and the integration of the basic models for each place was discussed to make the realistic landscape conform to the ideal needs. Moreover, the discussions also involved the characteristics of ideal landscape that are featured in resource, culture, structure, function, process, scale and region. In conclusion, ideal landscape in the Mount Lushan National Park was the product of the interaction between human and nature. Mount Lushan inherits the essence of Chinese traditional culture with a history of more than 1000 years; and it also absorbs the manna of the Western culture as well as the exchanges between nature and humanities together with the conflict and adaptation among different cultures. The natural landscape could be satisfied with the survival demand and cultural taste of mankind by the way of ecological planning.展开更多

The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt & Three Bays, One Core & Six Towns, Two Axes & Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.展开更多

It is found that 100.08km2(36%)of the total area is in the state of kilter,85.73km2(31%)of the total area is in the state of general,and 47.26km2(17%)and 15.48km2(16%)is in the relatively poor state and ideal state. According to landscape ecological structure,there are three landscape function areas being planned and designed. 1) Agricultural landscape function area: its developmental direction is tour agriculture and high benefit agriculture. 2) Eco environment protected function area:the direction of development and utilization of this region is to develop vigorously forest for soil and water conservation, and try to increase the rate of vegetation cover. 3) Forest landscape function area: rational cut and utilization of forest resources, space optimization disposal of category of forest, foster of forest and protection of wildwood will become the main development directions for this region. This study trys to provide scientific foundation for ecological restoration of the whole valley and its sustainable development.展开更多

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

Using published maps and documents and analyzing remote sensing data, an ecological inventory (GIS) was first developed. Based on these data, several criteria for land and water use suitability evaluation were produced. These were then overlayed to evaluate the entire region for several categories of land and water uses, and a suitability synthesis map was produced. This map became the basis for developing several possible concepts and plans for the sustainable development of the region. It is a timely and much needed approach in a rapidly developing country like China if development is to fulfill both present needs and allow future generations to fulfill theirs too.展开更多

This paper will probe an integrative methodologyfor achieving environmentally sound, economically productive, and ecologically responsibledevelopment in urban and industrial areas of China through ecological regulation. The central objec-tive is to promote highly efficient resource use rather than high speed development,harmonious sys-tem′s relationship rather than inflexible compartmentalization, and robust and vital self-organizationrather than bureaucrstic control. This ecological order is to be regulated through technological inno-vation,institutional reform, and behavioral incentives that promote positive economic dcvelopmentwhile mitigating negative environmental impacts.展开更多

However, due to global climate change and increased human activities, the natural environment in this region has undergone major alterations. In this work, we used the InVEST model to assess the spatial and temporal distribution of habitat quality and habitat degradation in the Sanjiangyuan region from 2000 to 2020. CA-Markov model was used to predict the land use changes under “natural development”(ND) and “ecological protection”(EP) scenarios from 2025 to 2050, and a comparative analysis of land use and habitat-quality changes was made in combination with the results of ecological zoning planning. We found that changes in human use land and bare land directly affect changes in habitat quality in Sanjiangyuan and are a major threat to habitat quality. Using the human-footprint index, Sanjiangyuan was divided into key protected areas, key restoration areas, and moderately developed areas. We compared the changes in habitat quality under two scenarios and discovered that under the EP scenario, the region of high habitat quality expanded, indicating that the EP scenario is beneficial for the sustainable development and conservation of biodiversity in Sanjiangyuan.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
