摘要
以2010—2023年新疆蔬菜种植面积及产量数据为基础,利用草谷比对秸秆资源量进行估算,并基于GIS分析法和空间层级矩阵法对新疆蔬菜秸秆的空间分布特性进行分析,以期为推进新疆蔬菜秸秆处理与高效利用、减少农业面源污染和助力我国蔬菜产业可持续发展提供参考依据。结果表明:2010—2023年新疆蔬菜秸秆理论产生量及可收集资源量均呈波动上升趋势,2015年后秸秆产量呈大幅上升趋势,2023年蔬菜秸秆资源量和可收集量均达到最大值,分别为147.20万t和73.60万t。根据GIS分析,新疆蔬菜秸秆资源呈“北低南高”的空间分布特征,秸秆主要产出地区位于新疆生产建设兵团、喀什地区、巴音郭楞蒙古自治州和阿克苏地区等。蔬菜秸秆播面单产最高地区为昌吉回族自治州。利用空间层级矩阵法分析发现,新疆生产建设兵团和昌吉回族自治州为新疆蔬菜秸秆产出的高丰裕地区,这些地区可以积极探索蔬菜秸秆利用的模式和建设蔬菜秸秆“收-储-运”体系集约示范区。
Based on the data of vegetable planting area and yield in Xinjiang from 2010 to 2023,straw resources were estimated by using the grass-grain ratio.The spatial distribution characteristics of vegetable straw in Xinjiang were analyzed through GIS analysis and a spatial hierarchy matrix method,in order to provide references for promoting the treatment and efficient utilization of vegetable straw in Xinjiang,reducing agricultural non-point source pollution,and contributing to the sustainable development of China′s vegetable industry.The results showed that the theoretical yield and recoverable resources of vegetable straw in Xinjiang exhibited a fluctuating upward trend from 2010 to 2023,with a significant increase in yield observed after 2015.In 2023,the total resource and recoverable amounts of vegetable straw reached their peak at 1.47 million tons and 736 thousand tons,respectively.According to GIS analysis,the spatial distribution of vegetable straw resources in Xinjiang was characterized by‘low in the north and high in the south’,with major production areas located in the Xinjiang Production and Construction Corps,Kashgar Prefecture,Bayingolian Mongolian Autonomous Prefecture,and Aksu Prefecture.Changji Hui Autonomous Prefecture recorded the highest unit area yield of vegetable straw.Spatial hierarchy matrix analysis revealed that the Xinjiang Production and Construction Corps and Changji Hui Autonomous Prefecture were key regions for abundant vegetable straw production.These areas could actively explore utilization models and establish intensive demonstration zones for the‘receiving-storage-transportation’system of vegetable straw.
