The nearest neighbors of each individual and the distances between each individual - neighbor pair in elaeagnus mollis communities were obtained by using the nearest neighbor ' s analysis . based on the primary results above , the spatial pattern and interspecific segregation in the communities were studied by x2 test with a subtable method of a n n nearest - neighbor contingency table 應用最近鄰體法判定每個個體的最近鄰體植株,得到每個基株-最近鄰體種對的距離,進而采用n n最近鄰體列聯(lián)表的截表法,研究了翅果油數(shù)群落的種間分離。
