摘要
[目的]探明茶叶产量时空演变特征和影响因素,可为优化四川省茶叶生产空间布局和区域可持续发展提供科学依据。[方法]基于1998—2018年四川省县域茶叶产量、茶叶种植面积和社会经济指标数据,采用空间自相关分析、重心模型和地理探测器等方法,对近20年四川省茶叶产量时空格局演变特征和影响因素进行分析。[结果]1998—2018年,四川省茶叶产量呈增长态势,空间分布差异明显,川西和川南产业带是茶叶生产热点区域,川东北产业带为冷点区域。全省茶叶产量重心以平均3.70 km/a的速度在四川盆地西南缘内移动,移动方向为“东-西-东”,呈“快-慢”的移动特征。农村人口、茶园面积、茶叶单产和路网密度是县域茶叶产量空间分异的主要影响因素,其中茶园面积为决定因素。[结论]四川省茶叶产量空间分布“西南高东北低”的态势更加显化,主要受茶园面积影响,随着茶园面积影响力减弱,应考虑转换第一驱动力以促进茶叶产业的可持续发展。
[Objective]To explore the characteristics and influencing factors of the spatio-temporal evolution of tea output can provide a scientific basis for optimizing the spatial layout of tea output.Thus,the regional development can be promoted.[Method]The characteristics and influencing factors of tea output in Sichuan Province in recent 20 years were analyzed by the spatial autocorrelation analysis,center of gravity model and geographical detector based on the data of tea output,tea planting areas and social and economic indicators in Sichuan Province from 1998 to 2018.[Result]The tea output in Sichuan Province showed an increasing trend,with obvious differences in spatial distribution in recent 20 years.The Western and Southern Sichuan industrial belts are hot spot areas for tea output,and the Northeast Sichuan industrial belt is a cold spot area.The tea output center of gravity moves within the southwestern edge of the Sichuan Basin at an average annual speed of 3.70 km,and the moving direction is“east-west-east”,showing a“fast-slow”movement.Rural population,tea garden area,tea yield and road network density are the main influencing factors for the spatial differentiation of tea output in the county,and tea garden area is the decisive factor.[Conclusion]The spatial distribution of tea output in Sichuan Province shows obvious characteristics of“high in the southwest and low in the northeast”,mainly affected by the area of tea gardens.As the influence of the tea garden area weakens,transforming the first driving force should be taken into consideration to promote the sustainable development of tea industry.
