1、Approximately half of the world's population relies upon biomass fuels - such as wood, dung and agricultural wastes - for everyday tasks such as cooking, drying crops and purifying water.───几乎半数的世界人口都依靠生物质燃料——木材,牛马粪便和农业废料等——来完成如煮饭,干燥农作物,净化水等日常生活活动。
2、The results were as follows:(1) The ramets density and population biomass at high level of soil moisture supply were higher than that of the population at low level of soil moisture supply.───结果表明:①土壤水分有效性高的种群,其子株密度和生物量大于土壤水分有效性低的种群。
3、From population level to functional group level, and then to community level, the yearly-variation of aboveground biomass minimizes gradually and stability increases.───从植物种群水平、植物功能群水平到群落水平,地上生物量的年度间变异性逐渐降低,稳定性逐渐增加。
1、Cutting also reduced the population biomass in aboveground.
