Study On Monitoring And Evaluating The Quality Of Forestry Environment With Diversiyt Of Insect Community

The species’ richness of soil insects, pollination insects and natural enemy, and the index ofinsect community diversity, to evaluate and monitor the renewable ability, the anti-interferenceand the ability to resist the harmful organisms, in three National Protection Zone: the Tian-muMountain, the Long Wang Mountain and the Bai Shan-zu Mountain in Zhejiang Province, then toevaluate and monitor the health degree of Forest ecosystem. The results is following:1.Through investigation, we find the kinds of soil indicative insects in Tian-mu Mountain,includes the species of Protura,Collembola and Diplura, the numbers of these soil indicativeinsects respectively are27,26and8, and the percentage of the total soil indicative insects inZhejiang Province respectively are72.97,65,61.54; similar results are0,2,2,in the Long WangMountain, but did not capture these insects in the Bai Shan-zu Mountain. We also find there are10species Bumblebees insect in the Tian-mu Mountain,5species Bumblebees insect in the LongWang Mountain,6species Bumblebees insect in the Bai Shan-zu Mountain, respectively are76.92%,38.46%,46.15%of total Bumblebees insect in Zhejiang Province.2. By the investigation of the indices of community diversity,we find the D value and Hvalue of major insect community in the Tian-mu Mountain is the highest, the E value in theTian-mu Mountain and the Bai Shan-zu Mountain are higher, the Long Wang Mountain is lowestcomparing with others in3indices of community diversity.3. The results suggest that the soil quality, the renewable ability, anti-interference ability toresist the harmful organisms is best in Tian-mu Mountain, and the community diversity is the most,the community structure is stable, and the secondary is the Bai Shan-zu Mountain, the lowest isthe Long Wang Mountain.To sum up, the health degree of forest ecosystem.of the Tian-mu Mountain is the bestcomparing with others.
