基于GIS的亚热带丘陵区果园景观分布格局及影响因素分析——以韶关市始兴县为例
|
摘要
以亚热带丘陵区的韶关市始兴县为研究对象,借助ArcGIS和Fragstats软件,研究果园景观空间格局、形态,并分析其影响因素。结果表明:(1)2016年始兴县果园面积较2006年稍有降低,且主要集中于始兴县中部;(2)2016年始兴县果园景观形状分布较2006年简单,果园破碎化程度较低,且具有较高的多样性与均匀性;(3)果园多集中于道路、居民点、水域的2km缓冲区范围内;(4)果园分布主要集中于海拔150～450 m范围内,在此范围之外,果园分布面积较小。
Taking Shixing County of Shaoguan City in the subtropical hilly area as the research object, the spatial pattern and shape of the orchard landscape were studied by ArcGIS and Fragstats software, and the influencing factors were analyzed. The results show that:(1) The area of orchard in Shixing County in 2016 is slightly lower than that in 2006, and it is mainly concentrated in the middle of Shixing County;(2) The shape distribution of orchard in Shixing County in 2016 is simpler than that in 2006, and the orchard is less fragmented;(3) The orchard is concentrated in the 2 km buffer zone of roads, residential areas and waters;(4) the orchard distribution is mainly concentrated in the elevation range of 150-450 m, where the elevation is Outside the range, the orchard has a small distribution area.
