摘　　要：特色经济林木的引入和扩种一直备受关注,为了更加科学合理地引入和扩种,以诸暨香榧为例,开展了基于气候、地形和土壤的种植适宜性区划研究。使用诸暨市48个气象站的气象数据,以及诸暨市地形、土壤和土地利用类型数据,采用主成分分析法、层次分析法、空间插值法和综合适宜度评价方法,计算香榧种植生境适宜度的空间分布,以进行种植区划。结果表明:诸暨市适宜种植香榧面积有624 km^(2),占诸暨总面积的27%;较适宜种植香榧面积有416 km^(2),占诸暨总面积的18%;不适宜种植香榧的面积有1271 km^(2),占诸暨总面积的55%。香榧适宜与较适宜种植的区域主要在诸暨市的西部、南部和东部,主要可扩种乡镇为东白湖镇、璜山镇和马剑镇;香榧不适宜种植在诸暨市中部盆地。相较于气候因素,土壤和地形因素更大程度上限制了香榧的种植。The introduction and expansion of characteristic economic trees had always been of great interest.In order to introduce and expand them more scientifically and reasonably,this study taking Torreya grandis in Zhuji City as an example,conducted research on the suitability zoning for planting based on climate,topography,and soil.Meteorological data from 48 meteorological stations in Zhuji City,as well as data on topography,soil,and land use types were used.The research employed principal component analysis,analytic hierarchy process,spatial interpolation methods,and a comprehensive suitability evaluation approach to calculate the spatial distribution of the suitability of T.grandis planting habitats for zoning purposes.The results indicated that the suitable planting area for T.grandis in Zhuji City covered 624 km^(2),accounting for 27% of the total area of Zhuji.Additionally,the moderately suitable planting area for T.grandis amounted to 416 km^(2),representing 18% of Zhuji's total area.Conversely,the unsuitable area for T.grandis cultivation encompassed 1271 km^(2),making up 55% of Zhuji's total area.The regions suitable and moderately suitable for T.grandis planting were primarily located in the western,southern,and eastern parts of Zhuji City,with the main expandable townships being Dongbaihu,Huangshan,and Majian.In contrast,the central basin area of Zhuji City was unsuitable for T.grandis cultivation.It was evident that soil and topographic factors played a more significant role in limiting T.grandis cultivation compared to climatic factors.
