摘  要：
基于2×2联列表,应用方差比率(VR)、卡方(χ2)检验、联结系数(AC)等指标对野生早樱群落中乔木层10个优势种群的种间联结性进行了研究。结果表明:10个优势乔木种群总体呈负的净关联;x2检验表明仅有4个种对表现为显著正联结,3个种对表现为有一定联结性;VR、χ2检验、AC3个参数计算的结果都较为一致,验证了该群落种对间独立性相对较强、相关性较弱的特点。现阶段,该群落种间联结性较为松散或呈负联结状态,一方面与群落所处次生演替初期有关,另一方面可能与各种群生物学特性有关。研究结果对野生早樱制定合适的保护与利用计划具有一定的科学参考价值。

摘  要：
Based on a 2×2 of contingency table,using of variance ratio(VR),x2 and the association coefficient(AC),the interspecific association of 10 major tree populations in the community of Cerasus subhirtella var.ascendens were analyzed.The result showed negative correlation of the association among 10 dominant tree populations in the C.subhirtella var.ascendens community;4 species-pair and 3 species-pair were obviously positive association and slightly association respectively;the value of VR,x2 test and AC were similar,which proved that the characteristic of interspecific association was obvious independency and weak correlation all over the community.The interspecific association was friable or negative,which indicated that on the one hand the community was in the stage of secondary forest and on the other hand it may be related to the ecological characteristic of investigated species.Based on the results,it can provide scientific information for design of an appropriate conservation strategy and utilization plan for C.subhirtella var.ascendens.
