基于GIS的栖霞市苹果种植区土地适宜性评价
Land Suitability Evaluation of Apple Planting Areas Based on GIS in Qixia City
摘要
Abstract
Taking Qixia City of Yantai as the research area, with the support of GIS technology, combined with analytic hierarchy process(AHP)and spatial interpolation,13 specific indexes were selected from 4 aspects of water supply,heat,soil and topography.The suitability of apple growing area in Qixia city was evaluated quantitatively,and some suggestions were put forward to adjust the distribution of apple growing area. The results showed that: (1) The suitability of Qixia's apple planting can be divided into four grades, namely, the most suitable, suitable, less suitable and unsuitable. The areas are 166.70 km2,295.59 km2,936.00 km2,607.84 km2,and account for 8.31%,14.73%,46.66%,30.30%,respectively.The most suitable areas are mainly distributed in northeast,southeast,southern valley and river alluvial plain area,the unsuitable areas are mainly distributed in middle, eastern mountainous region. (2)According to the combined weight analysis of analytic hierarchy process, surface water source, soil type, day and night temperature difference, elevation and slope are the main indexes to influence the planting suitability of apple in the region. (3)Compared with the second land survey data, it was found that the planting area of apple in Qixia was 391.20 km2, and the area of suitable area was 462.29 km2. The apple growing area is larger than the existing orchard area,and the apple planting industry still has a large development space.The hilly slopes north of the Baiyanghe plain and the Qingyang river alluvial plain area are of high natural origin but not the main apple distribution area,which can be properly developed as a new apple growing area.关键词
