Biogeochenlistry Characteristics on Tropical Forest Ecosystems in Jianfengling, Hainan Island, China

  • Received Date: 1992-01-07
  • According to the experimental results, the background value of both semi-deciduous monsoon forest and mountain rain forest ecosystems on the plant, Htterfall, surface soil, rock, throughfall, seepage water and stream were shown. The biogeochemical action on the elements capital aggregation and migration were synthetically analysed and estimated. Strong action of the biological absorption, decomposition, returned back and the leaching had been found. The substance exchange between the plant and the soil is strong. The tropical forest ecosystems keep a tightness balance on the substance cycle because the input content is more than the output. The intensity and velocity on the biochemical aggregation of the semi-deciduous monsoon forest ecosystem are larger and faster than that of the mountain rain forest ecosystem, but whose accumulation is contrary. It is obvious that the hydrochemical regulating function of the mountain rain forest ecosystem is superior to that of the semi-deciduous monsoon forest ecosystem. The characteristics on the elements aggregation and migration in the two type ecosystems have some differences. It is pointed out that the litterfall plays an important dominant part in the nutrient cycle direction and acts as a material base on the forest land fertility, which must be paid great attention to.

Abstract: According to the experimental results, the background value of both semi-deciduous monsoon forest and mountain rain forest ecosystems on the plant, Htterfall, surface soil, rock, throughfall, seepage water and stream were shown. The biogeochemical action on the elements capital aggregation and migration were synthetically analysed and estimated. Strong action of the biological absorption, decomposition, returned back and the leaching had been found. The substance exchange between the plant and the soil is strong. The tropical forest ecosystems keep a tightness balance on the substance cycle because the input content is more than the output. The intensity and velocity on the biochemical aggregation of the semi-deciduous monsoon forest ecosystem are larger and faster than that of the mountain rain forest ecosystem, but whose accumulation is contrary. It is obvious that the hydrochemical regulating function of the mountain rain forest ecosystem is superior to that of the semi-deciduous monsoon forest ecosystem. The characteristics on the elements aggregation and migration in the two type ecosystems have some differences. It is pointed out that the litterfall plays an important dominant part in the nutrient cycle direction and acts as a material base on the forest land fertility, which must be paid great attention to.
