Research on the Bio-ecological Characteristics of Daemonorops margaritae

This paper deals with the natural resources distribution, ecological and biological characteristics, growth and development rules of Daemonorops margaritae (Hance) Becc. D. margaritae is mainly distributed naturally in the tropical mountain rain forest, tropical evergreen monsoon rain forest, and subtropical broad-leaf evergreen forest. The density of distribution varies from 10～1700 stems/hm2 in the tropical mountain rain forest and the monsoon forest. D. margaritae is a clustering species with strong sprouting ability growing slowly in the early stage of 1～3 years old, then entering the stage of fast-growing at the age of 3 years old with an annual increment 1m in stem length and flowering and fruiting the age of 4 to 5. The clump is composed of uneven-aged shoots with different length. There are certain rules existing in the distribution of the stem length classes and ratio of its length to total length of a clump, which presents decreasing in the number of stems with raising in the length classes.
