Analysis on the Necessity and Feasibility of Implementing the Strategy of "Protecting Farmland in Flatland Areas and Constructing Mountainous Cities" in Yunnan Province

Yunnan is one of the most typical mountalnous provinces in western Chi-na. For the geographical features of mountalnous areas accounting for most parts and fIatIand areas accounting for smal parts, the contradiction between farmIand protection and construction guarantee is very prominent. In the first half of 2011, Yunnan Province estabIished creativeIy the strategy of ＆quot;protecting farmIand in fIat-Iand areas and constructing mountalnous cities＆quot; （hereinafter referred to as the strat-egy of ＆quot;constructing mountalnous cities＆quot;）, which was almed at protecting effectiveIy the Iimited and high quality arabIe Iand resources in fIatIand area and providing new construction area for new type of urbanization and industrialization, so as to achieve win-win situation between arabIe Iand protection and urbanization deveIopment. Im-pIementing this strategy in Yunnan Province is feasibIe, malnIy in the Iarge deveIop-ment potentials in the gentIe gradient between 8° to 25°. The gentIe sIope area be-tween 8° to 25° occupies 51% of the total Iand area in Yunnan Province, which is almost 140 times of the area of urban construction Iand in Yunnan in 2009. The surrounding areas of fIatIand or maln town in most counties （cities, regions） dis-tribute with different sizes of Iow hiI s and gentIe sIopes, thus mountalnous construc-tion Iand reserves are abundant, which benefits for impeI ing the strategy of ＆quot;con-structing mountalnous cities＆quot; in the Iight of Iocal conditions.

Problems of Land Use and Management in Development Zones and Enlightenment to Implementation of "Construction up to the Mountains" Strategy in Yunnan

ln the research, problems of land use and management in development zone were concluded, and analysis was made on the causes in order to draw lessons from land use and management in development zones. Furthermore, enlight-enment to implementation of ＂construction up to the mountains＂ strategy in the ar-eas similar to Yunnan was explored, which provides references for developing of＂construction up to the mountains＂ strategy and protecting of highly-qualified cultivat-ed lands in dam regions.
