At general planning level, the problems of the UGSS are mainly from the ignorance in the characteristics of urban nature spaces and the limitation factors of the urban planning system. Great importance is attached to the green spaces in the built area of city, but the green spaces in surrounding areas of the city is unnoticed. Furthermore, because the area of UGSS planning is strictly limited by the administrative zoning, the green space system loses its integrity and rationality in spatial patterns. The schedules of urban development planning mismatched the paces and progresses of the ecological restoration cycles. At special plan level, the problem of the UGSS in China is that the green spaces quantity was over emphasized but the rationality of their layouts is neglected.. Meanwhile, the requirement of the spatial structures and the green spaces layouts to balance between the urban development and the natural ecological environments is often ignored. With regard to the layouts in the UGSS planning practices, the existing problems are the compromising to the existing land-uses, the ＇filling in＇ approach to plan green spaces and an over-emphasis on the layout patterns.展开更多

This paper describes current situation of the emerging urban green space system and analyzes different characteristics between current green spaces and the old city or existing urban green space. Considering green space system planning in the downtown area of Gu'an County, advantages of the "network + patch" layout for green space systems in emerging towns are summarized to explore a green space structure suited to these towns.展开更多

It was found that the explicit supply of green feed production and the production areas of beef cattle and mutton sheep related to implicit demand of green feed production terminal are relatively concentrated and stable. The area of green feed production with scale comparative advantage accounts for a large proportion. The number of advantageous areas was less than that of beef cattle and mutton sheep. There were fewer matching advantageous areas between the explicit green feed supply and the implicit cattle and sheep consumption across China. According to the matching between explicit green feed supply and implicit beef and sheep consumption,China’s green feed production can be divided into four types. Therefore,based on grasping the current layout of green feed and beef cattle and mutton sheep production,according to the comparative advantages of each region,the government should make reasonable arrangements according to local conditions and adopt different development strategies for different regions.展开更多
