摘要： Land consolidation changes the land use types and then the biomass. The measure and calculation of biomass fore-and-aft land consolidation worked out by the sample plot method in terms of arbor, shrub, herbage plants and crop. The result shows that the biomass is increased 580 t after land consolidation, meaning the impression of land consolidation is remarkable in general. The results of monomial analysis are as follows: (1) the biomass of sparse forest is no changed fore-and aft land consolidation, but its ratio of biomass is reduced down 2.5% and its ecological influence is slightly weakened; (2) the biomass sum of manpower forest and sparse forest is increased up 6% after land consolidation, so that the total ecological influence of woodland is enhanced; (3) the waste grassplot is disappear of land consolidation, so that its ecological influence; (4) the total biomass of dry-land crop is all most no change, but its influence is reduced down 17.87%; (5) the total biomass of rice is increased up 477.94 t after land consolidation, account of 82.4% of increased amount and its total ecological influence is up to 14.12%. The results also show: (1) the structure and function of regional ecosystem will be changed by land consolidation and the biomass will be changed accordingly; (2) marked ecological influence will be induced from the biomass change, not only the natural ecosystem, but also the human ecosystem. © Maxwell Scientific Organization, 2014.
