项目摘要

In order to evaluate ecosystem rehabilitation of tropical rain forest by artificial planting, we investigate 1. growth and survival of planted seedlings, 2. ecophysiology of planted seedlings, 3. diversity and interaction of plants and animals, 4. genetic diversity, 5. physical and chemical property of soil and micro-organisms, and 6. awareness of local people in Bakam and Niah experimental forests, Sarawak, Malaysia. Our findings am summarized as follows.1. Secondary forest is the most suitable environment for planting judging from growth and survivorship of seedlings.2. Species characteristics in acclimatization and their proper site condition were clarified by the analysis of ecophysiology of seedlings.3. Evaluation of the effects of planting on diversity and interaction of plants and animals was not clear within ten years after planting.4. Genetic diversity and their local variation of few species in Dipterocarpaceae in Sarawak were revealed.5. Major environmental factor affects on growth and survivorship of seedlings was soil water and light in Niah and light in Bakam.6. Site selection for shifting cultivation as local people awareness was clarified but awareness for ecosystem rehabilitation was not cleared.From the achievement above, "in-Secondary Forest Planting Method", in which seedlings was planted in secondary forest established after the disturbance, was proposed as an effective planting method to rehabilitate degraded forests by clear cutting or shifting cultivation. And useful information, such as suitable species and site selection, was obtained to practice the method. Continuation of study, however, will be necessary to investigate the effect on diversity and interaction of plants and animals and awareness of local people.

为了评价人工造林对热带雨林生态系统的恢复效果，本文调查了1.种植幼苗的生长和存活，2.种植苗木的生理生态学，3.植物和动物的多样性和相互作用，4。遗传多样性，5。土壤和微生物的理化性质; 6.在马来西亚沙捞越的Bakam和Niah实验森林，提高当地人的认识。研究结果如下：1.从苗木的生长和成活情况来看，次生林是最适宜造林的环境.通过对苗木生理生态的分析，明确了该树种的驯化特性和适宜的立地条件.在种植后的10年内，对种植对植物和动物多样性和相互作用的影响的评价尚不清楚.揭示了砂拉越地区龙脑香科少数物种的遗传多样性及其地方变异.影响苗木生长和成活的主要环境因子是Niah的土壤水分和光照，Bakam的光照.在此基础上，提出了“次生林内造林法”，即在受干扰后建立的次生林内种植苗木，是一种通过皆伐或轮垦恢复退化森林的有效造林方法。并获得了实践该方法的有用信息，例如合适的物种和选址。然而，有必要继续研究，以调查对动植物多样性和相互作用的影响以及当地人民的认识。
