| 摘要: |
| 【目的】精细化了解余杭蜜梨种植适宜区域，为推广蜜梨种植、促进余杭特色农业增
收起到生产指导作用。【方法】基于气候和地形因子对浙江省余杭区蜜梨种植适宜性进行分
析与区划研究，选择 3 个气候因子，分别为≥ 10℃活动积温、年降雨量和年日照时数，选
择 2 个地形因子，分别为海拔高度和坡度。首先利用分布式模型，对所有气候因子进行空间
分布的精细化模拟。其次，利用层次分析法确定各个因子的权重，利用加权求和法建立蜜梨
种植适宜性区划评估模型。最后，结合各因子适宜度等级的量化指标，得到蜜梨适宜性综合
评价得分的精细化空间分布。【结果】根据余杭地区蜜梨种植适宜性综合评分，将种植区划
分为适宜、较适宜和不适宜 3 种。余杭区蜜梨种植较适宜区在各个乡镇都有分布，适宜区主
要分布在余杭西部地区，不适宜区较少，主要分布在百丈镇、鸬鸟镇、黄湖镇等地区的地形
背阴地带。【结论】通过适宜性分析评价，为余杭区蜜梨种植提供了地理位置选择参考。 |

| Abstract: |
| ［Purpose］Understanding the suitable area of Mili pear planting in Yuhang will
play a guiding role in promoting pear planting and increasing the income of characteristic
agriculture in Yuhang.［Method］Based on climate and terrain factors，the suitability of Mili
pear planting in Yuhang District of Zhejiang Province was analyzed and studied. Three climate
factors were selected，i.e.the active accumulated temperature which was bigger than 10℃，the
annual rainfall and the annual sunshine hours. Two terrain factors were selected，which were
the altitude and the slope. Firstly，the spatial distributed model is used to simulate the spatial
distribution of all climate factors. Secondly，AHP is used to determine the weight of each factor，
and weighted summation method is used to establish the evaluation model of Mili pear planting
suitability. Finally，the fine spatial distribution of the comprehensive evaluation scores of Mili
pear planting suitability is obtained by combining the quantitative indexes of each factor suitability
level.［Result］According to the comprehensive score of Mili pear planting suitability in Yuhang
area，the planting areas were divided into three kinds：suitable，more suitable and unsuitable.
The more suitable area for Mili pear planting in Yuhang District was distributed in all towns. The
suitable area was mainly distributed in the western part of Yuhang，while the unsuitable area
was less which was mainly distributed in the shady terrain of Baizhang town，Luniao town and
Huanghu town.［Conclusion］Through the suitability analysis and evaluation，it provides a
reference for the geographical location selection of Mili pear planting in Yuhang District. |
