摘　　要：以对城市森林生态效应的动态评价为目的,研究绿地和非绿地之间的物质交换特点与规律,描述和揭示植物群落的生态效应时空格局。试验对森林周边温度和湿度在空间和时间的梯度变化进行测试。结果表明,杨树林对其周边环境有着明显的降温和增湿效应,中午时段绿地生态场效应最高,下午测试时段对周边空气温湿度的影响与常规是逆反的。Taking the urban forest ecology effect dynamic assessment as the goal, research the material interchange characteristic and the rule between the green space and the non-green space, describe and promulgate the temporal and spatial patterns of the ecological effect affected by plant community. The experiment carried on the test to the gradient change of the forest peripheral temperature and humidity in spatial and time. The results indicated that the scale forests of poplar tree have the obvious temperature decrease and the humidity increase effect to its peripheral environment. The effect of ecological field is the highest at noon, and the influence of peripheral atmosphere temperature and humidity affected by poplar forest is retrograded to the convention in the afternoon.
