Ecological land is one of the key resources and conditions for the survival of humans because it can provide ecosystem services and is particularly important to public health and safety. It is extremely valuable for effective ecological management to explore the evolution mechanisms of ecological land. Based on spatial statistical analyses, we explored the spatial disparities and primary potential drivers of ecological land change in the Poyang Lake Eco-economic Zone of China. The results demonstrated that the global Moran's I value is 0.1646 during the 1990 to 2005 time period and indicated significant positive spatial correlation (p < 0.05). The results also imply that the clustering trend of ecological land changes weakened in the study area. Some potential driving forces were identified by applying the spatial autoregressive model in this study. The results demonstrated that the higher economic development level and industrialization rate were the main drivers for the faster change of ecological land in the study area. This study also tested the superiority of the spatial autoregressive model to study the mechanisms of ecological land change by comparing it with the traditional linear regressive model.
生态用地是人类生存的关键资源和条件之一,因为它能提供生态系统服务,对公众健康和安全尤为重要。探索生态用地的演变机制对有效的生态管理极具价值。基于空间统计分析,我们探究了中国鄱阳湖生态经济区生态用地变化的空间差异及主要潜在驱动因素。结果表明,1990年至2005年期间全局莫兰指数I值为0.1646,表明存在显著的正空间相关性(p<0.05)。结果还表明,研究区域内生态用地变化的集聚趋势减弱。本研究通过应用空间自回归模型确定了一些潜在驱动力。结果表明,较高的经济发展水平和工业化率是研究区域内生态用地变化较快的主要驱动因素。本研究还通过将空间自回归模型与传统线性回归模型进行比较,检验了该模型在研究生态用地变化机制方面的优越性。
