基于GIS的陕西省特色农业空间格局研究

Spatial pattern of characteristic agriculture based on GIS in Shaanxi Province

本文基于陕西省年鉴数据及农业产业统计数据,运用地理信息系统(GIS)空间分析、区位熵指数分析等方法,对陕西省特色农业空间格局进行研究。结果表明,陕西省特色农业呈“关中最为集中,陕南、陕北相对疏散”的分布特征;农业产业点在关中平原城市群区域的分布密度最大,在陕北长城沿线,陕南低山丘陵区分布亦较为集中;各类型特色农业产业的分布、密度情况相似,说明大部分农业发展相对较好的地区,具有发展多种不同特色农业产业的潜力;陕西省农业产业的聚集度总体朝好的方向发展,其中,渭南市、咸阳市特色农业产业的聚集效应最好,而商洛市、安康市的特色农业产业处于优势地位,但并不能有效推动整个产业发展,需加强上级政府部门的扶持力度。

This paper conducted a study on the spatial pattern of characteristic agriculture in Shaanxi Province based on data from the Shaanxi Statistical Yearbook and agricultural industry statistics,using research methods such as GIS spatial analysis and location entropy index analysis.The results indicate that the distribution of characteristic agriculture in Shaanxi Province presents a pattern of“most concentrated in Guanzhong and relatively dispersed in northern and southern Shaanxi”.The density of agricultural industry points is highest in the Guanzhong Plain urban agglomeration,while they are relatively concentrated along the Great Wall in northern Shaanxi and in the low hilly areas in southern Shaanxi.The distribution and density of different types of characteristic agricultural industries are similar,indicating that most regions with relatively good agricultural development have the potential to develop multiple types of characteristic agricultural industries.The concentration of agricultural industry in Shaanxi Province is generally developing in a better direction,of which Weinan City and Xianyang City have the best concentration effect of characteristic agricultural industry,while Shangluo City and Ankang City have advantages in characteristic agricultural industry,but it can not effectively promote the development of the entire industry,so it is necessary to get great support from the higher level government departments.
