| 摘要: |
| 利用判断矩阵法、线性加权求和法、GIS （地理信息系统，Geographic Information System）空间分析法和层次聚类分析法，基于地形数据、气候数据和土壤数据等11个指标，进行陕西省蓝莓生长的潜在适生区划研究。结果表明：1）陕西省具有大面积适宜蓝莓生长的立地条件，潜在适生区占总面积的88.56%。气候条件和土壤条件对其潜在分布区的限制作用较强，潜在适生区面积分别占总面积的39.54%和33.06%；2）从综合评价指标体系来看，陕西省蓝莓潜在适生区面积达到10.12×104 km2，占总面积的49.16%，主要集中在陕南浅山丘陵区和秦岭北麓山前区；3）运用层次聚类分析法，将潜在适生区分为3个亚区，非适生区分为2个亚区。其中，潜在适生区第1亚区具有较好的蓝莓适种条件，非适生区第2亚区的蓝莓种植条件最不理想。 |

| Abstract: |
| Based on the 11 indicators of three factors from topography,climate and soil in Shaanxi,judgment matrix,linear weighted sum method,spatial analysis method of GIS and hierarchical cluster analysis were used to evaluate the potential suitable planting area of blueberry in Shaanxi.The results showed that:1) In view of the topography,Shaanxi had a large area suitable for the growth of blueberries,and the potential suitability zoning area accounted for 88.56% of the total area in Shaanxi.Climatic and soil conditions had strong restrictions on the potential distribution areas of blueberry and its potential planting areas respectively accounted for 39.54% and 33.06% of the total area respectively.2) From the index system of comprehensive evaluation,the potential suitability zoning area of blueberries was 10.12×104 km2,accounted for 49.16% of the total area in Shaanxi,and mainly concentrated in the hilly region of south Shaanxi and north Piedmont region of Qinling Mountains.3) A hierarchical cluster analysis was used to divide the potential suitable zone into three subregions and divide the non-suitable zone into two subregions.The first subregion of potential suitability zoning displayed better conditions for blueberry planting,and there were the least ideal conditions for the blueberry planting in the second subregion of the non-suitable zone. |
