THE CHANGE OF CALORIC VALUES OF A MANGROVE SPECIES, KANDELIA CANDEL IN CHINA
红树植物秋茄热值及其变化的研究

Lin Guang-Hui,<br>光辉
生态学报 , 1991,
Abstract: Kandelia candet is a mangrove species which is distributed broadly in tropical and subtropical coast areas in China.The caloric values of its various plant parts range from 17.42 to 20.14 kJ/g for gross caloric value, and 19.48 to 21.98 kJ/g for ash-free caloric value, with the highest value for flower and leaf, and the lowest for root. The caloric value of leaf varies evidently with seasons, being the highest in October (19.7kJ/g), and the lowest in April (18.7kJ/g). The caloric value also varies with latitude of the areas where the samples were collected. Genenrally, the caloric values in spring, summer and fall decrease with the latitude increase,but that in winter increase with latitude increase. The charge patterns of caloric values for leaf revealt that K. candel possessed some special biological characters and cold-resistance which make it be able to grow and to be distributed in higher latitude areas than other mangrove species.

STUDY ON THE CALORIC VALUE AND ASH CONTENT OF SOME MANGROVE SPECIES IN CHINA
几种红树植物的热值和灰分含量研究

Lin Peng Lin Guang-hui,<br>,光辉
植物生态学报 , 1991,
Abstract: 本文主要研究我国东南沿海红树植物叶的灰分含量和热值含量的变化。在海南琼山沿海不同种红树植物之间,随叶灰分含量增加(7.11—9.8%)而干重热值减少(20.62—18.87kJ/g),但去灰分热值变化不大,在21.5kJ/g左右。同一种秋茄植物,在纬度较低(低于24 N)的地区,叶灰分含量较低,干重热值较高;在纬度较高时(高于24 N)则相反。秋茄幼树(1—7龄间)随年龄增长灰分含量下降,干重热值提高,而去灰分热值变化不大。热值季节变化中,夏秋较高,冬春较低。

海莲、秋茄两种红树群落能量的研究

Lin Guang-hui,Lin Peng,<br>光辉,
植物生态学报 , 1988,
Abstract: 本文应用热值测定,对中国两种典型红树群落,即海南岛的海莲群落及福建九龙江口的秋茄群落样品热值、群落能量现存量、能量固定量以及太阳能转化效率进行了测定和分析。结果表明:(1)红树群落各组分样品之间热值有一定的差异;一般叶、花的热值较高,而根、树皮的热值较低。(2)群落能量现存量海莲群落(1984年1月)高达1T8,627 kcal/m~2,秋茄群落为70,547 kcal/m~2,群落能量在不同组分以及不同高度层次上均有不同的分配比。(3)海莲群落(1983)、秋茄群落(1982)能量年净固定量分别为15,772kcal/m~2和10,456kcal/m~2,相应地对林地太阳光合有效辐射能的转化效率依次为3.01%和2.01%;红树群落比其他植物群落具有较高的能量固定能力及太阳能转化效率。
Review and Perspective on Hydrogen Stable Isotopes Technique in Tracing Plant Water Sources Researches
氢稳定性同位素确定植物水源的应用与前景

CAO Yanli,LU Qi,LIN Guanghui,<br>曹燕丽,卢琦,光辉
生态学报 , 2002,
Abstract: 介绍了氢稳定性同位素的测定方法和δD分析在植物水分来源研究中应用的原理,方法和典型案例,植物对不同水源的选择性和植物水分的δD分析被用于各种群落类型和环境中分析植物短期和长期的水分利用形式,甚至定量确定不同环境中各种植物对不同水分来源的利用,如白松、荒漠植物,河岸林和海岸植物,δD分析还用于研究植物与植物之间的相互作用。此外,氢稳定性同位素分析在古气候研究,植物光合途径,动物生理生态学和食物链等生态学领域也有着广阔的应用前景。
ISOLATION AND IDENTIFICATION OF N_2-FIXINGSTRAINS OF BACILLUS IN RICE RHIZOSPHEREOF THE YANGTZE RIVER VALLEY

Abstract: Rice rhizosphere soil samples were colected from 10 sites of 7 provinces in the Yangzi River Valley, and from the soil samples 16 endospore-forming strains with ARA (Acetylene Reduction Activity) were isolated, the nitrogen fixing ability was tested by the method of 15 N tracer and the atom l5 N % excess are ranged from 0.0297% to 0.4714%. The strains were identified as Bacillus licheniformis, B. subtilis, B. azotoformans, B. cereus, B. pumilus, B. brevis, B. megaterium, B, firmu
WHAT CAN WE LEARN FROM OXYGEN AND HYDROGEN ISOTOPE COMPOSITIONS OF TREE-RING CELLULOSE IN HIGHER PLANTS?
树年轮纤维素稳定同位素比率的生态学意义

植物生态学报 , 2002,
Abstract: Stable isotope ratios in tree-ring cellulose have been shown to be reliable recorders of changes in the ambient climate (Leuenberger et al., 1998). Thus, isotopic fractionations associated with both physical and biochemical processes during cellulose synthesis in higher plants (Epstein & Krishnaumurthy, 1990; Roden et al., 2000; Saurer et al., 1997a; 1997b; 2000) can be used as archives for past climatic indicators. Superimposed on the climatic induced isotopic signal are the long-term responses of plant physiological processes to past changes in environmental conditions including CO2 enrichment.
