Current Status and Stand Conditions of Plantation Resources Distribution of Dalbergia odorifera in Hainan Province
In order to understand the current situation of distribution and industry of Dalbergia odorifera T.Chen in Hainan Province and then provide scientific references for the development plan of the Hainan D.odorifera industry,distribution characteristics,seedling industry,planting bases,and processing industry were investigated through questionnaires and field surveys.The results showed that:(1)In Hainan Province,the total area of D.odorifera plantation was 6331.35 hm2,the total number of individual trees was 9817619,and the total storage volume was 123,598.62m3.(2)D.odorifera plantations were distributed in 18 cities and counties in Hainan Province,and the areas of the plantations in each city or county varied greatly.The largest distribution area was in Dongfang City,at about 1745.05hm2,accounting for 27.56％of the total area of the city,much high-er than the others.(3)The diameter and height of individual trees in the plantations were mainly concentrated in 0 ≤D＜10cm and 5m ≤H＜10m,respectively.(4)The distribution of artificial forests of D.odorifera in Hainan Province mainly consists of plains and plateaus,laterite soil,and thin soil layers;In terms of slope direction,slope,and slope position indicators,non slope direction,flat land,and flat slope are the main indicators.It is recommended to strengthen the breeding of new varieties,innovate cultivation techniques,and enhance the in-dustrial chain structure to promote the sustainable and healthy development of the D.odorifera industry.
