摘 要:大豆是中国最重要的粮食兼油料作物之一,在全国种植广泛,东北、华北是最重要的种植区域。随着人口的增长和人们生活水平的提高,中国对大豆产品的消费需求不断增加,但中国现有耕地面积有限,因此如何在现有耕地的基础上寻求高产量、高质量的大豆成为一个研究热点。在此背景下,本文以全国29个种植大豆的省、直辖市、自治区的大豆数据为基础数据,结合近年来的全国气象数据、气候资料、土壤数据,从基础数据中选取指标:生育天数、百粒重,从而基于GIS对各个指标进行空间自相关分析。分析了中国大豆生育天数、百粒重特点的分布,进而分析了中国大豆生产潜力的时空格局特征,揭示了中国大豆的生长特性及自身特性聚集区域,对未来大豆种植布局。Soybean is one of the most important food and oil-bearing crops in China. It is widely cultivated throughout the country, northeast and north China are the most important planting areas. With the increase of the population and the improvement of people living standard, China's consumption demand for soybean products gradually increases also. However,because China's existing arable land is limited, thus, how to seek for a kind of high yield and high quality soybean on the basis of the existing arable land becomes a research hotspot. In view of this background, this paper takes soybean data of 29 provinces,municipalities and autonomous regions that planted beans, as well as combing the national meteorological data, climate data, soil data in recent years, so as to select indicators from these basic data: days of growing period, distribution of hundred-grain weight, thus to make spatial autocorrelation analysis based on GIS. In addition, this paper analyzes the spatiotemporal pattern characteristics of Chinese soybean's potential productivity, as well as revels the growth characteristics and aggregation region of selfcharacteristic of Chinese soybean, which all plays a guiding role for the future soybean planting layout, efficient utilization of climate and land resources, even the realization of high and stable yield of soybean.
