Traditionally , pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen , so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used 传统上，风媒传粉被看成是这样的繁殖过程：其特征就是由一些随即事件的发生，在这些随机事件里，风的反复无常被大量的产生花粉所补偿，以至于新种子的最终产生被保证了，其代价是产生远远多于实际使用量的花粉。
Because the potential hazards pollen grains are subject to as they are transported over long distances are enormous , wind - pollinated plants have , in the view above , compensated for the ensuing loss of pollen through happenstance by virtue of producing an amount of pollen that is one to three orders of magnitude greater than the amount produced by species pollinated by insects 因为，潜在的危险，花粉粒在长途运输中所要遭受的潜在危险是巨大的，风媒传粉的植物，按上述观点来看，补偿了在偶然事件中伴随产生的花粉损失，通过的优点是，生产出的花粉数量比那些依靠昆虫传粉的植物所产生的花粉数量大一到三个数量级。
The increase of waste from cities , the heavier of agricultural chemical pollution , the serious pollution produced by poultry waste , as well the pollution produced with the development of township enterprises have affected the organic production of agricultural ecosystem , reduced the quality of produce , weakened the soil ecological process , destroyed biodiversity , weakened the function of climate regulation and disaster - reduction , decreased insect pollination and the effect of control pest 城市污染物排放增加，农业化学品污染加重，农村畜禽粪尿污染成灾以及乡镇企业污染发展影响了农业生态系统有机质生产，降低了农业产品品质，减弱了土壤生态过程，破坏了生物多样性，减弱了气候调节与减灾功能，减少了动物传粉与有害生物控制效应七项生态服务功能。
