【摘要】：为合理规划猕猴桃种植布局,基于中国大陆地区主栽的美味猕猴桃和中华猕猴桃的种植分布信息以及1981-2010年2084个气象台站数据,综合生理存在需求和品质形成选取了影响猕猴桃种植分布的9个潜在影响因子,结合最大熵(MaxEnt)模型和ArcGIS软件,构建了猕猴桃潜在种植分布与气候因子的关系模型,研究了影响猕猴桃种植分布的主导气候因子及适宜范围,并利用存在概率这一综合反映各主导因子作用的指标,对不同的气候适宜区进行了划分。结果表明:影响中国区域猕猴桃种植分布的主导气候因子按照贡献率大小依次为最冷月平均气温、年日照时数、年相对湿度、最热月平均气温、无霜期和降水量,限制性因子是无霜期和最冷月平均气温。猕猴桃的潜在适宜区主要分布在102oE以东,24-36oN区域。其中,高气候适宜区主要包括四川中东部、重庆中西部、贵州高原、湘西南和陕西秦岭北麓。湖南、湖北和重庆等省市气候适宜度较高,还有较大的发展空间,而目前种植较为集中的秦岭北麓和川西北种植区应适当控制发展规模,着力提升品质和效益。
[Abstract]:In order to plan the planting layout of kiwifruit reasonably, based on the planting distribution information of Actinidia deliciosa and Actinidia chinensis in mainland China and the data of 2084 meteorological stations from 1981 to 2010, Nine potential factors affecting the distribution of kiwifruit cultivation were selected according to physiological requirements and quality formation. The relationship between the distribution of potential cultivation and climate factors was established by combining the maximum entropy Max Ent model and ArcGIS software. In this paper, the dominant climatic factors and their suitable ranges affecting the distribution of kiwifruit cultivation were studied, and the probability of existence was used as a comprehensive index to reflect the effects of each dominant factor. The main climatic factors affecting the distribution of kiwifruit cultivation in China are the coldest monthly mean temperature, the annual sunshine hours and the annual relative humidity according to the contribution rate. The hottest monthly mean temperature, frost-free period and precipitation, limiting factors are frost-free and coldest monthly mean temperature. The potential suitable areas of kiwifruit are mainly located in the 24-36oN region east of 102oE. The central and western parts of Chongqing, the Guizhou Plateau, the southwest of Hunan and the northern foothills of the Qinling Mountains in Shaanxi Province, Hunan, Hubei and Chongqing provinces have relatively high climate suitability, and there is still considerable room for development. In the north foot of Qinling Mountains and northwest Sichuan planting area, the scale of development should be controlled properly, and the quality and benefit should be improved.
