The ecological consequences of shifting cultivation in the semideciduous monsoon forest zone and different methods of catting and regeneration in the mountain rain forest zone have been studied in Jiaruengling, Hainan Island. Permanent plots have been set up to observe the rainfall, throughfall, interception, seepage, run-off, soil fertility and microclimate. The variations after forest cutting on hilly lands and the ecological changes after shifting cultivation have been analyzed. During the cultivation period,...

The ecological consequences of shifting cultivation in the semideciduous monsoon forest zone and different methods of catting and regeneration in the mountain rain forest zone have been studied in Jiaruengling, Hainan Island. Permanent plots have been set up to observe the rainfall, throughfall, interception, seepage, run-off, soil fertility and microclimate. The variations after forest cutting on hilly lands and the ecological changes after shifting cultivation have been analyzed. During the cultivation period, ecological conditions worsened, and during the period out of cultivation the conditions improved. Deterioration was due to the increases in air and soil temperatures, the decrease in relative air humidity, the decreases in capability of soil water storage and soil fertility; and. the loss of soil and water. Following regeneration and the shifting of cultivation, the tending selection cutting was the best and the diameter limit cutting was better than clearcutting. Forest conservation and utilization were also discussed from point of view of soil and water loss.

本文对海南岛尖峰岭半落叶季雨林带的游耕农业及热带山地雨林不同采伐方式与更新方法的生态后果进行了对比实验与调查研究。观测结果说明,游耕农业耕垦期的小气候急剧恶化,水土流失严重,涵水能力降低,地力趋向减退,撩荒期有所好转。采育择伐的更新与生态后果优于径级择伐,更显著优于皆伐。对热带森林的保护与利用对策,提出了建议。

Four aspects of soil deterioration in the tropical forest had been demonstrated according to experiment of the shifting cultivation on ecological efficiency of the semi-deciduous monsoonforest at Jianfengling, Hainan Island.

Four aspects of soil deterioration in the tropical forest had been demonstrated according to experiment of the shifting cultivation on ecological efficiency of the semi-deciduous monsoonforest at Jianfengling, Hainan Island. With losing of the litterfall the supplemental source of the soil fertility and the hydrologic function are declined; soil and water erosion severe; the ability of water transportation and the storage capacity are decreased; soil fertility degraded owing to deterioration of the soil physico-chemical properties.It is suggested that the shifting cultivation system must be rid of practice establishing an agro-forest system based mainly on the woody plants, drawing up resonable overall and management for the tropical forest, preventing from slash-and-burn cultivation, carrying out of planting technique of ecology, so as to maintain the soil fertility and the protection of soil resource of the tropical forest.

This paper summarized the multidiscipline and comprehensive research on the tropical forest ecosystem in Jianfengling region, Hainan Island, during 1979-1986. The background investigation, permanent observation plots and experimental plots have been adopted. The paper consists of 7 parts: the biological gene pool in northern edge of world tropic; ecological series strudy; water and heat regime of tropical forest; nutrient cycling in tropical forest; ecological consequence of shifting cultivation; and regeneration and succession after afforestation. There are 1668 plant species of 798 genus, 198 families more than 4000 identified insect species of 26 orders and 260 species of identified macro-fungi. The ecological series from seashore to mountain top consisted of xerophytic thorn shrub, savanna, tropical semideciduous monsoon forest, tropical evergreen monsoon forest, tropical mountain rain forest and mossy forest have been studied by means of comprehensive and comparative description.

本文系1979—1986年采用本底调查、小区实验和定位观测等方法对海南岛尖峰岭热带林生态系统进行多学科综合研究的总报告。本报告共分7部分:世界热带北缘的丰富的生物基因库;生态系列研究;热带林水热状况;热带林物质循环;游耕农业生态后果;热带林采伐后的更新与演替。长期本底调查查明本区有植物1668种,隶属 198科798属;已知昆虫26目 4000余种,已知大型真菌260种。对由海滨至主峰的滨海有刺灌丛、稀树草原、半落叶季雨林、常绿季雨林、山地雨林,山顶苔藓矮林所构成的生态系列进行了组成、结构、土壤、林分生长等特征及其形成的自然地理环境进行了综合性比较研究。
