Human activities makes important role on deepen impacts, so it must be taken into consideration in disaster preventions.

由于水旱灾害与社会经济发展相互影响，社会经济发展对水旱灾害既有抑制作用又有促发作用，因此在进行防灾建设时，必须注意社会进步和经济发展带来的新的致灾因素，注意防灾建设与生态环境和灾害之间的关系。

It suggested that the AEBSF delayed leaf senescence though inhibition the endopeptidase activity and influence the SOD and POD activity.Native PAGE with gelatin as substance in gel showed the activities of isoenzyme 3 and 4 were inhibited partly by AEBSF treatment on leaves.It implies that the two isoenzymes are type of serine endopeptidase and may play an important role in cucumber leaves senescence. Degradation of protein and changes of endopeptidase isoenzymes in cucumber Cucumis sativus L.

活性电泳显示，黄瓜叶片中检测到6条内肽酶同工酶，其中4条(CEP2，3，4，6)为丝氨酸型内肽酶，内肽酶抑制剂AEBSF抑制了叶片中丝氨酸内肽酶同工酶的活性，而ABA使丝氨酸内肽酶CEP2，3，4的活性显著增强，再次暗示了丝氨酸型内肽酶在黄瓜叶片衰老以及叶片Rubisco降解中具有重要作用，而且除了丝氨酸内肽酶外，可能还有其它因素参与了衰老的调控。
