摘要
1987～1989年,在云南镇源热区研究紫胶园生物群落与环境的关系;群落内种间的相互影响;紫胶园间种粮食作物的作用;不同群落结构与产量、产值的关系。结果表明:胶粮间作群落、乔灌混交群落,能较好地利用自然条件和种群间的有利关系,使群落的经济产品总量较对照提高2.4～4.4倍,产值较对照提高1.9～2.0倍。
This paper deals with the biological community types from the eco-economic viewpoint in several lac plantations different at Zhenyuan county, Yunnan province from 1987 to 1989,studies have been conducted on the relationship between biological communities and their environments, between different community to their structures productions and values and on the correlations among different species as well as functions of intercropping crops in the communities. The results have shown that the economic output and its value of lac-grain-intercropping and tree-shrub-mixed forests are 2.4~4.4 and l.9~2.0 times higher than those of the checks respectively.
