摘　　要：选择河南境内黄淮海平原主体区域的商丘市民权林场与梁园区黄河故道国家森林公园的林农复合生态系统,测定了生态系统1年内各月份的空气离子的日进程,分析其空气负离子的变化规律。结果表明：空气负离子浓度在不同林农复合生态系统中有一定差别,在系统内各点差别较小;杨树生态系统的日进程格局基本一致,表现出近似的＂U＂型,一天中的高峰值出现在09：00～10：00与17：00前后;泡桐生态系统的日进程虽然在09：00～10：00也出现高峰值,但随后表现出单调下降趋势。研究结果为林农复合生态系统生态效益计量提供基础依据。Minquan State Forest Farm and the National Forest Park of the Ancient Yellow River course of Liangyuan District are in Shangqiu City, which form the main part of Huang-Huai-Hai Plain in Henan Province. Several agroforestry ecosystems there were selected to measure the daily process of air negative ion in different months of a year. Based on these data, the change of air negative ion was analyzed. The concentration of air negative ion varied among different agroforestry ecosystems but with little difference between sites within the same ecosystem. All the daily process of air negative ion in the Populus ecosystems showed a U-shape pattern, where the maximum values occurred at 09：00 ～10：00 and 17：00, respectively. In the Paulownia ecosystem, the maximum of air negative ion concentration also occurred at 09：00 ～10：00, but then straightly declined afterword. The result could provide a reference and base for ecological benefit measurement of an agroforestry ecosystem.
