农牧交错区城市可持续发展问题与对策

农牧交错区是我国重要商品粮基地和畜牧业基地的衔接区,集中了我国大部分贫困县（市）,在我国经济重心转移和农村经济发展和生态建设中扮演重要角色。该地区的生态环境的脆弱性孕育着城市生态环境问题,是制约城市可持续发展的“瓶颈”。随着西部大开发和社会经济可持续发展战略的实施,迫切要求作为区域增长极的城市走可持续发展之路。本文对城市可持续发展研究背景、内涵和理论框架进行探讨,并剖析农牧交错区生态环境的特殊性和城市生态环境问题（如水资源短缺、城市基础设施严重落后、城市环境污染较严重、城市产业结构单一,城市间产业关联度较低等）的基础上,提出实现城市可持续发展的针对性对策。

PROBLEMS AND COUNTERMEASRES OF URBAN SUTAINABLE DEVELOPMENT IN AGRICULTURE- STOCKBREEDING INTERLACED AREA

Agriculture-stockbreeding interlaced area is important grain and stockbreeding base, important region for ecologic construction and economic development of rural area. It becomes an idealistic researching area for global change and sustainable development because of its weak natural environment and strained man-land relation. For a long time, agriculture and animal husbandry have been the mainstay industries of the region, which have made great contributions to regional economic development and improvement of living standard of local people. However, the ecologic environment in the area has already shown a tendency of deteriorating resulting from the extensive development. On the long run, the benefit from the traditional development mode cannot compensate the expense in the developing process, so it is time to change the method of economical increment and to lead a way of urbanization. The fragile eco-environment of the area is background of urban ecological problems, such as water resources shortage, pollution expansion, backward infrastructure, irrationally concentrated industry structure and so on, which have already become the "bottle-neck" of urban sustainable development, and which are also important causes of the concentrating of poverty counties. With the implementing of the strategies of the Great Development of Western China and sustainable development, the cities, as the regional poles, are urgently required to develop in a sustainable way. This paper discusses the background, connotation and theory frame of urban sustainable development in the agriculture-stockbreeding interlaced area, and then analyze the key urban environment problems and its particularity in sustainable development. At last, based on the analysis the status quo of this region, the paper brings forth the thoughts and countermeasures on realizing the urban sustainable development in the areas.
