environ.动物物种再引进animal species reintroduction Attempts made to prevent the extinction of threatened species and populations by reintroducing them in their natural habitat. The reintroduction of species in a region requires a preliminary study to establish the reasons of their disappearance and the modifications that might have occurred in the biotopes (将受威胁物种再引进到自然栖息地以防止物种灭绝。 物种的再引进需要对它们消失的原因以及其生态环境的更动进行初步研究。)
environ.动物物种引进introduction of animal species Animals which have been translocated by human agency into lands or waters where they have not lived previously, at least during historic times. Such translocation of species always involves an element of risk if not of serious danger. Newly arrived species, depending on their interspecific relationships and characteristics, may act as or carry parasites or diseases, prey upon native organisms, display toxic reactions, or be highly competitive with or otherwise adversely affect native species and communities (被人类机构移位到所在地以前,至少有历史可查时期,没有存在于土地或水中的动物。这种物种移位总会涉及一定的风险,有时甚至于是严重危机。取决于所引进物种的种间关系和特点,他们可以作为或携带侵食本地生物的寄生虫或疾病,引起毒素反应,或者与本地物种相比具有高度竞争力,或以其他方式严重影响本地物种和群落。)
expl.可能引起争论的是、对实际现场条件所引起气体的浓度测量、可提供一种改进的方法It might be argued that measurements of gas concentrations arising from real field conditions could provide an improved approach,however such programs would need to cover a wide range of conditions and explosives and could be prohibitively expensive and time-consuming

environ.植物物种引进introduction of plant species Plants which have been translocated by human agency into lands or waters where they have not lived previously, at least during historic times. Such translocation of species always involves an element of risk if not of serious danger. Newly arrived species may be highly competitive with or otherwise adversely affect native species and communities. Some may become a nuisance through sheer overabundance. They may become liable to rapid genetic changes in their new environment. Many harmful introductions have been made by persons unqualified to anticipate the often complex ecological interaction which may ensue. On the other hand many plants introduced into modified or degraded environments may be more useful than native species in controlling erosion or in performing other positive functions (被人类机构移位到所在地以前,至少有历史可查时期,没有存在过的土地或水中的植物。这种物种移位总会涉及一定的风险,有时甚至于是严重危机。与本地物种相比,新引进的物种可能具有高度竞争力,或者它们可能以其他方式严重影响本地物种和群落。在新环境中它们可能变得易于进行快速的基因突变。对可能随之发生的复杂的生态学反应,由于人类作出的预测不合格,已经做出了很多有害的引进。另一方面,许多被引入退化或改变过的环境中的植物可能会比本地植物在控制水土流失或发挥其他积极作用方面更有优势。)
