泰国国土面积514,000平方公里,森林面积200,000平方公里,占国土面积的39%。森林面积中170,000平方公里为可伐林,而红树林为287,000公顷,占森林总面积的1.43%。泰国森林面积在近20年来减少800公顷,约占14％。红树林也不例外,由于各种开发,使其急剧减少,成为有待解决的问题。笔者有机会参加东京农业大学综合研究所杉二郎博士率领的调查团,于1981年和1984年两次约四个月的时间调查了泰国的红树林。现将收集的资料及调查结果介绍如下:
Thailand has an area of 514,000 square kilometers and a forest area of 200,000 square kilometers, accounting for 39% of the country’s territory. Of the forest area, 170,000 square kilometers are forkelling forest, while mangroves are 287,000 hectares, accounting for 1.43% of the total forest area. Thailand’s forest area decreased by 800 hectares in the last 20 years, accounting for about 14%. Mangroves are no exception, due to a variety of development, to make it drastically reduced, has become a problem to be solved. The author had the opportunity to participate in a survey team led by Dr Sugiriro, General Research Institute of Tokyo Agricultural University, and surveyed Thailand’s mangroves twice in 1981 and 1984. The information collected and the survey results are as follows:
