Abstract:This paper recorded the destruction of natural vegetation at Baodao Xin Cun in recent thirty years, and its influences on the following aspects. 1. The vegetation is becoming lower and lower gradually, and the species of its composition fewer and fewer; the kinds of woody plant have been reduced to 102 as compared with that which is composed of 211 at the beginning of 1950’S. 2. Wild animals have become fewer as well, 21 species of birds have no longer existed. 3. The soil fertility is declining. As a result, the output of crop is decreasing and the outgrowth of natural vegetation is becoming poor year by year. In some quadrats, the fresh weight of plants above the ground is just over half of one kilogram per square meter. With the decling of soil fertility, some sciophiles specially fond of rich soil are dying away and some arid-enduring plants are sneaking in.
