城乡生态经济交错区土地管理若干理论问题研究

A theoretical research on land resource management in the urban rural eco economic fringe

鉴于城乡生态经济交错区土地资源利用和土地管理的重要性，探讨了城乡生态经济交错区的特征，认为其自由度高、生态脆弱、城乡相互作用强烈、生态经济要素水平梯度大，不仅土地生产力高，而且可能引起严重的资源冲突，导致相关生态经济问题和农地城市流转；提出了城乡生态经济交错区土地管理的目标是生态的可持续性、经济的可持续性与社会的可持续性；土地管理的原则为限制性原则、主导性原则。

Land resource use and land management in the urban rural eco economic fringe(UREEF) are in disorder at present. With the speedup of urbanization, the high quality farmland will be encroached and lead to a series of eco economic problems. This paper gives a preliminary research on land management issues in the urban rural eco economic fringe such as the eco economic features, the significance, the targets and the principles. 1)The eco economic features of the UREEF. The higher degree of freedom, ecological fragility, strong interaction between rural and urban areas, greater vertical gradient of eco economic element distribution not only form higher productivity of land, but also cause severe resource conflicts which in turn give rise to related eco economic problems and rural urban land conversion. 2) The significance of land management in the UREEF. Because of poor land management and land planning, some associated eco economic problems emerge. So strengthening land management in the UREEF can practically deal with the two policy targets: food security and urbanization, and theoretically enhance the growth of interdisciplinary management subjects. 3) The targets of land management in the UREEF: ecological sustainability, economic sustainability and social sustainability. The principles of land management in the UREEF: constraint principle, dominance principle, equity principle and territory principle.
