采用空间序列代替时间变化的方法研究广东廉江谢鞋山野生荔枝的种群结构，并采用方差/均值比的t检验法判定其分布格局。结果表明，野生荔枝种群呈随机分布，种群内低龄和高龄植株较少，中龄级植株较多，种群更新能力不足，存活曲线接近Deevey-Ⅰ型，属衰退种群，亟待保护。
The population structure of wild Litchi chinensis in Mt. Xiexie, located in Lianjiang, Guangdong province, was analyzed by the method of spatial variability for time series, while the spatial pattern was studied by means of t-test of variance/mean value radio. The results indicated that the spatial pattern of wild L. chinensis population was random distribution. As a result of the number of low age-class and high age-class was fewer than that of middle age-class in the population of wild L. chinensis, the population regeneration was insufficient, and the survival curve was closely to Deevey-Ⅰpattern. In other words, wild L. chinensis population of Mt. Xiexie was declining type and should be protected.
