摘  要:
利用地统计学方法研究了不同时期朝鲜球坚蚧 (DidesmococcusKoreanusBorchs)若虫及黑缘红瓢虫 (ChilocorusrulidusHope)幼虫种群的空间分布格局和空间相关性 .结果表明 ,不同时期朝鲜球坚蚧若虫种群和黑缘红瓢虫幼虫种群的半变异函数均可拟合为球型 ,其空间格局为聚集型 ,在小尺度上 ,空间变异主要是由其空间自相关引起的 ,且不同时期格局变化不明显 ,变程分别为 9.5 6~ 15 .70m和 18.83~19.74m之间 .黑缘红瓢虫种群与朝鲜球坚蚧种群之间具有很强的追随关系 ,说明黑缘红瓢虫种群是朝鲜球坚蚧种群的优势天敌

摘  要:
The spatial pattern and correlation of Didesmococcus koreanus Borchs and Chilocorus rubidus Hope in different periods were investigated with geostatistics. The results showed that the semivariogram of Didesmococcus koreanus Borchs and Chilocorus rubidus Hope could be described by spherical model, indicating that their spatial pattern were in agreement. The spatial variation was arosed by its spatial autocorrelation in small scales, and the spatial pattern had no apparent changes in different periods. The range varied from 9.56~15.70 m and from 18.83~19.74 m, respectively. The amount and spatial distribution of Chilocorus rubidus Hope was closely related to that of Didesmococcus koreanus Borchs, which revealed that Chilocorus rubidus Hope was the dominant natural enemy of Didesmococcus koreanus Borchs.
