摘要: 栖霞市是中国苹果主产区之一,光、热条件及地形是影响当地苹果分布和品质的主要因素。基于生态适宜性,建立苹果园地单项土地利用优化模式,是栖霞市农业结构调整所需要的。本研究在对光、热条件及地形空间分布模拟的基础上,以土地利用现状类型为景观介质表面,利用GIS的空间信息处理技术,建立了苹果园地最小累积阻力模型(MCR),探讨山区苹果园地单项土地利用优化的技术途径。将栖霞市划分为极度适宜区、高度适宜区、适宜区和初度适宜区4个适宜分区,各区的面积分别为20466、38392、97367和41301 hm2,极度适宜区和高度适宜区面积占县域面积的29%,苹果园地开发的适宜性较大。MCR模型为当地苹果产业开发和农业结构调整提供决策依据。

Abstract: Qixia City of Shandong Province is one of the major apple production areas in China, while light and heat conditions and terrain are the key factors affecting the distribution of local apple orchard and the apple quality. It is necessary to optimize the local land use pattern of apple orchard, based on the principles of ecological suitability for the agricultural structure adjustment of the City. On the basis of the simulation on the spatial distribution of light and heat conditions and topographical parameters, and choosing the present land use types as the landscape medium surface, this paper established a minimum cumulative resistance (MCR) model by using GIS technology, and explored the technical approaches for the optimization of apple orchard land use in the mountainous area of Qixia City. Four zones were divided, i.e., most suitable, highly suitable, suitable, and the sub-suitable, occupying 20466, 38392, 97367, and 41301 hm2, respectively. The acreage of the most and highly suitable zones for apple planting was 29% of the total. This study showed that the MCR model provided decision-making basis for apple industry development and agricultural structure adjustment of Qixia City.
