The characteristics of biodiversity of yellow river delta are as follows : the vegetation structure is simplex and coverage is lower, which is characterized with obvious younger nature and abundant wetland ; the flora composition is simple, the plants usually could resist against salt and drought ; the xerophytes and meso - xerophytes are abundant, there are many mutual species with inner mongolia, which incarnated the biology corridor function of yellow river ; there are many animal species belong to national protected species, so the significance for biodiversity protection is great
黃河三角洲地區生物多樣性主要表現出如下特點：植被結構簡單、覆蓋度低、生態系統年輕性特點和濕地生態系統特點明顯；植物種類少、常具有抗鹽、抗旱特性；旱生、中旱生植物以及與內蒙古共有植物種類多，充分體現了黃河的生物廊道作用；主要保護動物種類多，生物多樣性保護意義重大。
