摘要
通过收集19个生物气候变量的栅格数据及白酒企业的地理分布数据,利用核密度估计(KDE)法绘制白酒生产企业密度分布图,进而分析其与生物气候变量之间的相关性,并提出贵州产业布局与资源配置策略。结果表明,贵州白酒生产企业主要集中在合肥市,且企业的空间核密度值与19个生物气候变量及数字高程模型(DEM)均呈高度显著相关性(P<0.001),其中与DEM呈负相关,表明白酒企业更多的分布在低海拔地区;与日较差、等温性、最湿月份的降水量和最暖季度的降水量呈负相关,说明温差较小、降水适中稳定的地区更有利于酿酒微生物发酵环境的稳定性;而与温度季节性、最暖月份的最高温度、最冷月份的最低温度、年温差、最湿月份的最低温度及最暖季度的平均温度均呈正相关,表明白酒企业偏好分布在气候冷暖分明、高温高湿且冬季不极寒的区域,这种自然条件更有利于发酵动力的激活与酿酒微生态的形成。因此,贵州白酒产业在未来发展中应将生物气候变量纳入产业规划,构建气候适应性评价体系,科学划定适宜发展区与限制开发区,提升选址与资源配置的精准性。
The density distribution map of Baijiu production enterprises was drawn using the kernel density estimation(KDE)method by collecting the raster data of 19 bioclimatic variables and the geographical distribution data of Baijiu enterprises,then the correlation between it and bioclimatic variables was analyzed,and the industrial layout and resource allocation strategies for Guizhou were proposed.The results showed that the Baijiu production enterprises in Guizhou were mainly concentrated in Zunyi City,and the spatial kernel density values of the enterprises were highly significantly correlated with 19 bioclimatic variables and the digital elevation model(DEM)(P<0.001),among which there was a negative correlation with DEM,indicating that Baijiu enterprises were more distributed in low-altitude areas.It was negatively correlated with the diurnal range,isothermality,precipitation in the wettest month and precipitation in the warmest quarter,indicating that areas with smaller temperature differences and moderate and stable precipitation were more conducive to the stability of the fermentation environment for brewing microorganisms.It was positively correlated with the temperature seasonality,the highest temperature of the warmest month,the lowest temperature of the coldest month,the annual temperature difference,the lowest temperature of the wettest month and the average temperature of the warmest quarter.This indicated that Baijiu enterprises prefer to be distributed in areas with distinct cold and warm climates,high temperature and humidity,and not extremely cold winters.Such natural conditions were more conducive to the activation of fermentation power and the formation of the brewing micro-ecology.Therefore,in the future development of the Guizhou Baijiu industry,bio-climate variables should be incorporated into industrial planning,a climate adaptability evaluation system should be established,suitable development zones and restricted development zones should be scientifically demarcated,and the accuracy of site selection and resource allocation should be enhanced.
