摘  要：
【目的】进行板栗生态适宜性的综合评价,为山东省板栗栽培区划提供科学依据。【方法】根据板栗生长发育与气象和土壤条件的相关分析,提出了板栗适宜性评价指标为10个生态因子(年平均气温、1月份平均气温、7月份平均气温、年极端最高气温、年极端最低气温、≥10℃的积温、无霜期、年降水量、年日照时数、土壤pH值)。以山东省的140个县(市、区)为研究的区域单元,采用模糊综合评判法,建立了板栗栽培的生态适宜性评估模型。【结果】借助地理信息系统(GIS)技术,计算了综合评估指数的分布规律,将山东省板栗栽培区域划分为优势、适宜和不适宜3个等级,完成板栗生态适宜性区域分布示意图。【结论】山东省优势、适宜和不适宜板栗栽培的地域面积分别为14.91%、32.01%和53.08%。

摘  要：
【Objective】Ecological suitability evaluation can provide a scientific basis for the determination of optimal cultivation region for chestnut in Shandong.【Method】Based on the analysis of the relationships among the growth and development of chestnut,meteorological factors and soil conditions,this study proposed comprehensive regionalization indices including 10 ecological factors(the mean annual temperature,the mean temperature in January,the mean temperature in July,the annual extreme maximum temperature.the annual extreme minimum temperature,the annual accumulated temperature above 10 ℃,frost-free period,the annual precipitation and the annual sunshine duration,soil pH value).Method of the fuzzy comprehensive evaluation was adopted to establish the evaluation model of ecological suitability and 140 counties(cities,areas) in Shandong province were involved in the research.【Result】The distributions of comprehensive evaluation indices were calculated based on GIS.The regional distribution of ecological suitability in chestnut was completed and divided into 3 classes including superior,suitable and unsuitable regions.【Conclusion】 The studies suggested that the superior,suitable and unsuitable regions for chestnut cultivation account for 14.91%,32.01% and 53.08% respectively.
