摘要
蝴蝶的种群数量正受到越来越严重的威胁,概述了目前中国蝶类多样性的主要威胁因子,主要有生物因素、人为因素和自然因素。其中主要威胁因子是人为因素,包括环境污染、栖息地破坏、农药喷洒、人为捕捉,这些威胁因子对蝴蝶威胁巨大,不仅降低蝴蝶种群数量,可能导致某些蝶种灭绝。次要威胁因子有寄主植物破坏、放牧、旅游开发、城市化和气候变暖等人为因子,还包括低温、洪水等自然因子和天敌危害、蝴蝶自身因素等生物因子。这些因子是导致自然界中蝴蝶越来越少,是蝴蝶正常生存的制约因素。
Threat on population of butterfly was becoming more and more serious. This article summarized themain threat factors, including biological factors, human factors and natural factors, on diversity of butterfly inChina. Main threat factors included environmental pollution, habitat destruction, pesticide spraying, artificialcapture, all belonged to human factors. These threat factors not only reduce population of butterfly, but alsomay cause extinction of some species. The secondary threat factors included human factors like host plantdestruction, graze, tourism development, urbanization and climate warming, natural factors like lowtemperature and flood, and biological factors like natural enemy and own factors of butterfly. These factors alsoled to the reduction of butterfly numbers and were restricting factors to normal survival of butterfly.
