中国热带次生林区森林资源及社会经济状况——广东古兜山林区调查报告

Forest Resources and Social Economic Situation of Tropical Secondary Forest Region of China——The Investigation Report of the Gudou Mountain Forest Region of Guangdong

为更好地开展热带次生林经营,在国际热带木材组织"旨在提高经济和生态效益的热带地区次生林经营研究与示范"项目(ITTO PD 294/04)的资助下,对较为典型的中国热带次生林———广东古兜山林区开展了森林资源与社会经济状况的相关调查,其结果认为:中国热带林区的热带森林除自然保护区外,几乎都以低产低质的次生林状况存在,这类林分质量普遍较差,很少开展经营活动,因此缺乏经济和生态效益。林区居民主要依靠政府的生态公益林补偿、砍伐林木、出租林地供商品林经营以及农耕等获得收入,生活仍然处于比较贫困的状态,人均年收入仅3 780元(约合556美元)。林农普遍的愿望是将次生林地改种以桉树为代表的速生丰产商品林经营,以获得较高的经营效益,次生林的保护仍然面临巨大的压力。

In order to improve the tropical secondary forest（TSF） management, with the support of the International Tropical Timber Organization（ ITTO）, the investigation of forest resources and social economic situation was carried out in a typical TSF forest region ＇ Gudou Mountain areas of Guangdong, which was one of the subject of ＂The Study and Demonstration of the Management of Secondary Forests in Tropical Regions ior The Purpose of Enhancing Economic and Ecological Benefits＂, （ PD 294/04 Rev. 4 （F） ）. The result from which we considered that ： Chinese tropical forest areas, with the exception of protected areas, almost existed as low-yield and low quali- ty secondary forests, and activities of forest management had seldom developed, so it lacked of economic and ecological benefits. The residents＇ incomes were mainly from the government＇s compensation for ecological forest, deforestation, rent of commodity forest land, and farming etc. Their life was still poverty and the annual per capita income was only 3 780 yuan （ about 556 U. S. dollars）. The generally desire of the forest farmer was developing fastgrowing and high-yield commodity forest such as Eucalyptus to obtain higher management benefits. So China was still facing great pressure in the protection of TSF.
