以重庆主城区山地公园林缘的光照、湿度、温度和植物多样性为研究对象,采用样带研究法,分析和探讨其林缘生境的光照、湿度、温度和植物梯度变化规律.发现山地公园光照从缘外到缘内呈现出骤减-缓慢下降-基本不变的梯度变化规律;空气湿度从缘外到缘内逐渐增高,白天温度与光照变化规律成正相关;植物多样性从缘外到缘内表现出先增加后减少的特性;初步得出重庆主城区山地公园林缘边缘效应宽度基本在6～14m之间波动,且边界木缘外3m到缘内2m是边缘效应强度值最大的区域.提出山地公园林缘植物配置应遵循从缘外到缘内依次配置阳性、半阴性、耐阴和阴生植物这一规律.%Based on the light, humidity, temperature and plant diversity on the mountain park's forest edge in Chongqing, this paper analyzes and discusses the changes of light, humidity, temperature and plant gradient on the mountain park's forest edge with transect method, and found the light of Mountain Park from outside edge to inside edge presented sudden decrease - slowly decrease - essentially constant changes of the gradient; air humidity increased gradually from outside edge to inside edge; daytime temperature positive correlation with variation of light; plants diversity presents the characteristics of first increasing and then decreasing from outside edge to inside edge. This paper preliminarily concluded the width of edge effect wave between 6 ～ 14m fundamentally of mountain park in main city proper of Chongqing, and the region of 3m outside edge to 2m inside edge is the edge strength values of the largest regional effect. This paper presents that the plants disposition on the mountain park's forest edge should follow the law which is by tums lightdemanding plant, semi-shade-loving plant, shade-enduring plant, shade plant, from outside edge to inside edge.
