Selecting the excellent species of energy-forest tree is the technical key to developing and constructing energy forest.In this research,ecolo- gic theory and advanced biologic techniques were adopted.For the first time,comprehensive characteristic indices were put forward,such as biologic yield,growth increment,calorific value,specific gravity,eco- physiologic features,morpho-anatomic features,multiple uses(all-round beneficial results of energy,ecology and economy),etc..These indices were regarded as the quantitative...

ABSTRACT A comparative study was conducted to determine the water ecophysiology ex-isting in complex stands as against in pure stands of oiltea camellia,and in the upper part ofthe complex canopy as against in the lower part.Results showed that complex stands werebetter not only in helping to increase the wflter-holding capacity of the soil but also inbuffering water losses;that air temperature was higher in the upper part of.the complexcanopy as against in the lower part.Results showed that complex stands were better not on-ly in helping to increase the water-holding capacity of the soil but also in huffering waterlosses;that air temperature was higher in the upper part of the complex canopy than in thelower part,but a lower relative humidity was found in the upper part than in the wer part;that transpiration in complex stands was vertically distributed with the most intense transpi-ration occurring in the part of the canopy at from 50 to 75 percent of the canopy beight;andthat the monthly chanee in transpiration intensity with the complex stands took on a double-peak curve,while the daily change was expressed by a single-peak curve.KEY WORDS Camellia oleifera;Complex stand;Water ecophysiology.

通过对油茶复合林与纯林之间、复合植冠层上下之间的水分生理生态比较研究,分析论述了油茶复合林水分生理生态特征。结果表明:①复合林林地与纯林林地比较,不仅提高了土壤的持水性能,而且对水分的散失具有“级冲性”。②复合植冠层上下气温和相对温度有较明显差异,上部温度高、下部温度低;上部相对湿度小,下部相对湿度大。③复合植冠的蒸腾作用是垂直分层的,其最强区位于相对高度0.5~0.75之间。④复合林的蒸腾强度月变化有两次高峰值,而日变化呈单峰曲线。

Abstract This paper summarized the achievements of research in ecology and its benefits of the coastal shelterbelts in the last ten years in the respects of the physiological and ecological characteristics of shelterbelts including respiration, evaporation, water content and their effects on tree growth and nutrient status .The structure composition regression equation of biomass,decomposition speed of litters and nutrient distribution of the shelterbelt systems were also discussed.Adaptability of trees to the environment,the effects of environment on forest growth,and the damage of natural disasters and pollution to the forest were analysed.The functions of pratection forest in soil and water conservation,climate regulating, soil improving etc. were discussed as well.
