AN ANALYSIS OF ECOLOGICAI CHARACTERISTICS OF EVERGREEN BROAD-LEAVED FOREST IN THE TIANTONG NATIONAL FOREST PARK,ZHEJIANG PROVINCE, CHINA

This paper studies on the ecological characteristics including environmental condition, flodstic composition, physiognomy and structure of Evergreen Broadltavecl Forest (EBLF) in the Tiantong National Forest Park, Zhejiang Province according to the, widely investigation. The following conclusions can be obtained :1. The Tiantong National Forest Park is located in the northern edge of middle subtropics. Irs warm and damp climate, complex topography., as well as deeper and richer soil provide the fa-vorisble ecological environment for the conservation and development of the BELF.2- Based on the data statistics, there are 73 families, 156 genera ar.J 246 species of vascular plants within 10,000 m3 samples. The floristic composition is very rich and complex. The numbers of family, genus and species in the flora occupy a higher ratio in the vascular plants of Zhejiang Province and China. The results indicate that the EBLF in this park is closely related to that of the tropics, especially southeast tropics. However, the higher percentage of the temperate elements should be one of the essential characteristics of the EBLF in this park.3. The physiognomy of the EBLF is regular and dense, it is largely dependent on the life forms and the leaf features. The evergreen phaenerophytes with microphyll, mesophyll, herbaceous, leathery and simple leaves are the main components of determing the physiognomy and structure of the EBLF.4. The further analysis of above ecological characteristics show the transitional nature of this EBLF from tropical forest to temperate forest. The author provide some suggestions of strengthening the measures of conservation and management.
