基于“基准农田”系数的云南省城镇上山规模初探（英文）

The Scale of Constructing Mountainous Cities in Yunnan Province based on “Benchmark” Farmlands

为了积极保护耕地资源,充分保障粮食安全,2011年云南省委省政府提出了城镇上山战略,从而充分利用低丘缓坡土地,转变建设用地方式。但是云南省社会经济发展空间上存在非均衡性,且自然地理条件相差较大,这就要求推进差异化的城镇上山规模。本文提出了耕地保护粮食安全下的城镇上山规模控制问题,运用粮食安全下"基准农田"测算云南各州(市)的"基准农田"系数,然后根据人口预测学和规划学的原理,测算新增建设用地需求量,据此"基准农田"系数与新增建设用地面的乘积确定城镇上山控制规模。该研究对指导城镇上山战略和避免建设用地占用粮食安全战略的耕地有重要意义。

In 2011, Yunnan provincial committee and government proposed the strat- egy of constructing mountainous cities in order to protect farmlands and guarantee crop safety, which makes full use of hills and gentle-slopes and transforms land use pattern. However, social and economic development performs unevenly in Yun- nan, supplemented by varied geographical conditions, so that constructing mountain- ous cities should proceed as per local conditions. The research proposed the con- trol of constructing mountainous cities provided crop safety under the principle of farmland protection and measured the quantities of demanded construction lands ac- cording to science of population prediction and ekistics, based on which the control scales of constructing mountainous cities were determined by multiplying basic farm- land coefficient and the area of newly increased construction lands. The research is of significance for guiding the construction of mountainous cities and avoiding the occupation of construction lands on farmlands.
