Results11 separated constituents were identified, the contents of 3 compounds were over 20%. The main constituents in extracts were Bis(2-ethylhexyl) phthalate (21.51%), Nonacosane (25.73%), Stigmastan-3,5-dien (25.73%).

结果从海南裂叶山龙眼叶超临界二氧化碳20 MPa压力提取物中共分离出11个组分，全部进行了鉴定，其中含量高于20%的有3个，为邻苯二甲酸二(2-乙基己基)酯（21.51%）；二十九碳烷（25.73%）；3，5-二烯豆甾烷（25.73%）。

Olethreutes leucaspis Meyrick was one of the main pests of longan and litchi at shooting stage.

三角新小卷蛾是龙眼、荔枝抽梢期主要害虫之一。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined.

在不同光照梯度，即100％自然全光照（natural sunlight，NS）、37.3％NS、15.5％NS、4.2％NS、1.6％NS和0.6％NS的人工遮荫条件下，研究了西双版纳季节雨林冠层树种绒毛番龙眼幼苗的早期生长和定居后的生长特点。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.

生长早期的幼苗基径和复叶数随遮荫程度的增加而降低；主根长、根冠比、总干重和单株叶面积均以37.3% NS处理最大；比叶面积随遮荫程度的增加而增大，而相对生长率则降低；幼苗株高在0.6% NS下增长最快，表明种子中贮藏的营养物质对幼苗的早期生长可能具有重要作用。37.3% NS处理对定居后绒毛番龙眼幼苗的生长最有利，幼苗的株高、基径、复叶数、叶轴长、复叶最多小叶数、单株叶面积、相对生长率和净同化率均在37.3% NS处理下获得最大增长；幼苗总干重随光照强度的减弱而降低；比叶面积在15.5% NS处理时最大。

The curve of diameter distribution was showed J shape in Swietenia macrophylla pure stand and Dimocarpus longan pure stand. We used maximum likelihood method and percentile estimator method to analysis stand structure.

纯林之直径分布中，桃花心木林与龙眼林林分其直径分布呈现倒J型分布；柚木、摩鹿加合欢、相思树林、苦楝林型其直径分布呈现复合型分布；黑板树林型及白鸡油林型为左偏态分布。

There were 31 kinds of landuse types in Hsin-Hua Forest Experiment through aerial photography interpretation. In pure forest, the volume of Swietenia macrophyllas stand was 193.45 m3/ ha which was higher than other stands. And in mixed forest, the highest volume was 163.40m3/ha by Swietenia macrophylla- Dimocarpus longan mixed stand.

藉由航空照片判释之结果得知，新化林场土地利用型共计31种，纯林蓄积量最大者为桃花心木纯林，其蓄积量为193.45 m3/ ha；混交林型中，则以桃花心木-龙眼混交林型蓄积量最高，蓄积量为163.40 m3/ ha。
