基于2005~2017年湖北省74个县域面板数据,构建基于交通权重的空间权重矩阵,利用空间杜宾模型,实证研究耕地利用转型影响农民增收的空间溢出效应,并进一步揭示该溢出效应呈现的具体规律与特征.研究表明:(1)耕地利用转型各形态和农民收入水平都具有显著的正向空间自相关性;(2)农民收入水平的空间自回归系数ρ为0.65,表明相邻县域农民增收存在正向空间溢出效应,即本县域农民收入增长1%,相邻县域农民收入将会增长0.65%;(3)相邻县域间的空间溢出效应主要靠耕地数量、农业劳动力和基础设施投入形态变化驱动,其中,农业劳动力形态变化产生的空间溢出效应占总效应的69%,耕地数量形态占15%,基础设施投入形态占12%.因此,应注意提升县域间耕地利用系统协同性,利用其空间溢出效应促进湖北省各县域共同发展、农民收入协同提高. 相似文献

This study investigated the water quality variation spanning 30 years (1986–2017) in 16 catchments of Hong Kong against different urbanization indices, namely, built area fraction; population; and product of population and built area fraction. Pearson correlations of three different periods of time (1988–1990, 1998–2000, and 2015–2017) indicated that water quality trends were dependent on the urbanization index. Total solids, nitrite-nitrogen, total phosphorus, electrical conductivity, dissolved oxygen, and flow rate had significant deteriorative trends (Pearson r > 0.5 and p < 0.05) with population and product of built area and population. Results also interpreted that built area fraction and product of built area and population were the worst and best indices that represented urbanization and/or its impacts, respectively. Mann-Kendall test for the entire 30 year period showed that water quality had improved with time with respect to certain water quality parameters (e.g., dissolved oxygen, ammoniacal nitrogen and total suspended solids). The results portrayed that although the urbanization of catchments had increased with time, the river water quality with respect to many parameters showed signs of improvement and the legislative measures implemented seemed to be effective in controlling pollution. 相似文献
