Under such an impact , the properties of the soil ecosystem characterized by nonlinear responses to forced conditions may show a tendency of catastrophe and trigger a more serious environmental risk 在长期保持高强度利用和过量农用化学品投入的情况下，以非线性响应为特征的土壤生态系统特性有可能出现突变状态，并引起更大的环境风险。
Cyanohydrins are biologically active compounds used in synthesis of - amino alcohols , - hydroxy ketones and - hydroxy acids , which have importance as fine chemicals , pharmaceuticals and agrochemicals 氰醇是合成-氰基醇类， -羟基酮类及酸类化合物的重要生物活性物质，这些化合物又是精细化工、制药和农用化学品领域的重要原料和中间体。
The united states will be monitoring closely china s implementation of its wto commitments , including its commitments relating to the protection of data submitted to obtain regulatory approval of pharmaceuticals and agricultural chemicals 美国将密切监视中国执行其对世贸组织承诺的情况，包括对为申请许可而提交的药品和农用化学品资料给予保护的承诺。

Agricultural intensification plays an important role in stabilizing the food production in china , while bringing about an increasing negative impact on the soil and eco - environment as a result of the long - term highly - intensive land use and agricultural chemical overuse , thus leading to degradation of soil physical , chemical and biological properties , which are demonstrated as soil nutrient imbalance , soil acidification , pollutant accumulation , and biodiversity deterioration and posing serious stress and threat to the ecosystem per se and the environment 摘要集约化农业对保障我国粮食安全发挥了巨大的作用，但其长期的土地高强度利用和农用化学品过量投入的负面影响也日益显现，导致的以土壤养分失衡、土壤酸化、有害物质积累、生物多样性衰退等为主要表现形式的土壤物理、化学和生物学退化，给生态系统本身与环境都带来了巨大压力和严重威胁。
