Geostatistics Analysis of Spatial Parterns of Kytorhinus immixtus Population
摘要
Abstract
[ Objective ] The paper was to study the spatial distribution pattern and spatial correlation of egg nasses and larvae population of Kytorhinus immixtus. [ Method ] By using statistical principles and methods, the quantity of eggs and larvae population of K. immixtus was investigated, and the obtained data were analyzed. [ Result ] The circular model was the best fitting model for egg masses and larvae population of K. immixtus, and the spatial distribution pattern was aggregated distribution with a? spatial correlation, the range of spatial dependence varied from 18. 899 to 62.922 and 13.464 to 47.455. The distribution pattern of egg masses and larvae population of Kytorhinus immixtus were simulated by using ordinary Kriging method, and the result showed that their distribution had obvious aggregated character, the aggregation intensity in the core area of plaque was significantly higher than that in the edge. There was anisotropy of aggregation intensity, the aggregation intensity from northeast to southwest direction was significantly higher than that from northwest to southeast direction. [ Conclusion ] The spatial distribution pattern of egg masses and larvae population of K. immixtus was aggregated distribution, and the increase of plant distance and patch fragmentation had a certain control effect on the occurrence of K. immixtus population.关键词
