Abstract

Abstract: With the ecological public welfare forest in Sanya city as the research object and on the basis of the structure,stability and functions of the forest,an index system of forest ecological evaluation was constructed.Based on this,the forest ecological level of the study area was evaluated with the small class as the evaluation unit.The results showed that the six indicators of forest ecological evaluation factor weights from big to small were:forest volume(0.25),forest naturalness(0.20),forest community structure(0.20),forest health level(0.15),canopy density(0.10) and the average tree height (0.10). Four overall regional ecological levels were at the medium level,and the ecological level is the highest in Baoan area.The level of forest ecology in the four regions was Baoan area >Nahui area >Qingfa area >Zhanan area.

Key words: forest ecological index, ecological public welfare forest, forest ecological evaluation, Sanya City
