第一节 农业植物群落生态工程 一、热带地区农业植物群落生态工程 在自然界里,各种植物组成各式各样的群落;一定地区的各种群落组成该地区的植被。自然形成的植物顶极群落的结构复杂,一般层次多、单位面积植株多度大。尤其是热带雨林群落结构最为复杂,其中乔木层2—3层,灌木和草本植物有6—7层之多,木本群落以多优势种混交型为主。几十年来,人们一直在设
Section I Ecological Engineering of Agricultural Plant Communities I. Ecological Engineering of Agricultural Plant Communities in Tropics In nature, various plants make up a wide range of communities. Various communities in certain areas make up the vegetation in this area. Naturally formed plant climax community complex structure, the general level and more, the unit area of large plants. In particular, the tropical rain forest community structure is the most complex, of which 2-3 layers of arbor layer, shrubs and herbs have 6-7 layers as much, woody community dominated by multi-dominant mixed type. For decades, people have been setting up
