Taking Dawan Yard in Tianwan Village, Wanzhou District, Chongqing City as an example, construction dilemmas in mountain area are analyzed, such as backward rural economy, low farmers' incomes, the loss of labor population, the decentralization of village construction land, small-scale village construction land, and the lack of technology and funds for the improvement of village living environment. Combining with the development opportunity of Dawan Yard in Tianwan Village, it puts forward three planning countermeasures of "smart contraction": smart utilization of village resources, smart allocation of public service facilities and smart inheritance of village memory. We hope to provide a new way to revitalize the countryside via case analysis of Dawan Yard.展开更多

Thus “landscape ecological construction” has evolved in China. This approach adds spatial elements and alters landscape pattern to strengthen inter-ecosystem linkages, improve functioning of damaged ecosystems, and increase productivity and stability of the whole landscape. Five examples of managed landscapes in China are presented: dike-pond systems in a river delta; multi-pond system in a rice paddy landscape; field-grass-wood grid system on unstable sand dunes; shelterbelt network in a crop field area; and field-grass-wood mosaic system on highly erodible hilly farmland. These indicate that ecological conditions can be improved along with increased economic production. Altering landscape structure and ecological flows by introducing small landscape elements in distinct spatial patterns is considered a key to the results. This reshaping of the land has focused on changing patch size, regularity of arrangement, biological and hydrological corridors, and networks, the matrix and grain size. It suggests that such changes can increase negative feedbacks and increase stability. Finally, planning and design principles are pinpointed for the landscape ecological construction process.展开更多
