Abstract:

运用空间统计学相关方法对中国及31个省区2001-2013年两大食用菌主要品种(香菇和平菇)的时序演变规律和空间分布变化进行分析。结果显示,中国食用菌产业发展迅速,总体差距缩小,但区域间差异明显;食用菌主产区由原来的东部沿海、中部、华南和东北为主的格局,逐渐演变为以东部沿海、华中、华北和东北地区为主的新格局,福建的“中心”地位被河南和山东所代替,“南菇北移”的现象异常明显;香菇和平菇在空间上均呈现明显的空间正相关性和集聚现象,平菇的集聚现象更为明显。
This paper analyzes the spatial and temporal evolution of two main edible fungi species——the shiitake mushroom and oyster mushroom,from 31 provinces in China between 2001 and 2013 by employing the method of spatial statistics.The result shows that the edible fungi industry is developing rapidly in China,the general gap is narrowing,but the difference between regions is evident.The main edible fungi producing areas is gradually evolved from the eastern coastal,central,south China and northeast China to the eastern coastal,central China,north China and northeast of China,and Fujian’s core location status was replaced by Henan and Shandong provinces.The phenomenon of edible fungi producing areas changing from south to north is obvious at the same time.Shiitake mushroom and oyster mushroom have the obvious spatial correlation in space and agglomeration phenomenon,and the aggregation of oyster mushroom is more obvious than that of shiitake mushroom.
