摘要
黔中喀斯特区域随着地质历史的演化，高原的生成，喀斯特的发育，气候的变化，形成复杂多样的地貌特征及适宜的生态环境，是新第三纪以后随高原隆起而在东南亚洲起源的月鳢得以在区内各类型水域广泛分布，繁衍后代，源远传留的特殊所在。大量使用农药和化肥，水土污染与日俱增，以及不断地乱砍滥伐，毁林开荒，过度放牧，土壤大量流失而淤积和填塞各类型水域，并隔离成若干个相对独立的生活小区，自然生境日愈恶化，是月鳢自然资源日渐衰减乃至濒危的重要原因。
The earth had mad of complex diveriform Landform features and propriate ecological factors in Centre Karst region of Guizhou province wity geology deology,cause to had formed plateau and changed climate.following channa asiatica(Linnaeus) could distibuted widely,Lived and breeded over different types of water region it who origined in the southeast Asia at the new Tertiary.the article studies that channa asiatica(Linnaeus)has been affected ecological malignanting.as lots of agriculture chemical and fertilizer has been supplied that cause water and soil to be polluted.Seviously by days.forest was daruayed by mankind cause amount so reducing that trend to in imminent for channa asiatica(Linnaeus).So I put ways and countermeasure conservation forward channa asiatica(Linnaeus)that is supply agreculture chemical and fertilizer method of scientic ,Protect pland and earth by law and establish nature area for it.
