本期《热带林业》特刊专门介绍海南岛上鲜为人知的热带石灰岩生态系统,也介绍了邻近地区石灰岩生境保护的一些经验,题材主要来自2006年3月于海南昌江县举办的海南石灰岩生境保护研讨会的内容。我们希望藉本特刊唤起公众对海南石灰岩生态系统的关注、突显其独特和珍贵之处,继而与各位共商最恰切的保护、恢复及永续管理方针。我国西南部的石灰岩地貌早已闻名于世,其壮观的喀斯特地貌历来启发了无数艺术家的灵感,然而它的价值却不只于此。石灰岩是由微小海洋生物的外壳慢慢沉积而成,不但影响全球四分之一人口的供水。

We s.udied human perceptions.on the management of bamboo-tree gardens.in two villages.with contras.ing agroecological conditions.in the upper Citarum bas.n. We undertook interviews.to reveal perceptions.on the tenure, function, and management s.rategies.of multi-layered agrofores.. Owners.in a village located lower in the bas.n perceived the gardens.more pos.tively than thos. in an upland village, where market pres.ures.were felt more keenly and for a longer period. There was.not always.a direct correlation between perceptions.and behavior with res.ect to bamboo-tree garden management. However, we concluded that an unders.anding of human perceptions.could provide valuable ins.ght to the proces. of formulating s.rategies.that might be effective in minimizing the convers.on of bamboo-tree gardens.to more intens.ve and les. ecologically divers. agricultural s.s.ems. s.ecifically, s.nce the villagers.retained a s.rong cultural perception of the heritage value of the bamboo-tree gardens. they would likely be res.ons.ve to cons.rvation efforts.that increas.d the economic value of the gardens.and reduced the opportunity cos. of not converting them to production that is.more intens.ve or other land us.s.

Niche theory is.one of the mos. important ecological theories. It is.widely applied to analyzing s.ch phenomena as.competition among, and evolution of, urban ecos.s.em functional modules. This.paper des.ribes.a s.udy concerning＇different functional modules.of Kaifeng city urban ecos.s.em. Niche theory and techniques.were us.d to analyze the changes.of thes. functional modules.in the period 1994-2003. The res.lts.s.owed that, in the period 1994-2003：（1） Niche value of the atmos.heric environment and urban vires.ence modules.increas.d, while niche value of the water environment and s.und environment modules.decreas.d; （2） niche value of the tertiary indus.ry module increas.d, niche value of the s.condary indus.ry module decreas.d, while niche value of the primary indus.ry module s.owed little change; and （3） niche value of the infras.ructure, res.urce dis.ribution, and production ＆ s.cial s.curity modules.increas.d, while niche value of the population module decreas.d. This.s.udy may contribute to macros.opic planning of urban functional modules. economic development, and environmental protection.

s.as.nal metrics.and environmental res.ons.s.to fores.ry s.il s.rface CO2 emis.ion effluxes.among three types.of lower s.btropical fores.s.were cons.s.ently monitored over two years.with s.atic chamber-gas.chromatograph techniques.among three types.of lower s.btropical fores.s. Res.lts.s.owed that annual CO2 effluxes.(s.L) reached 3942.20, 3422.36 and 2163.02 CO2 g·m-2·a-1, res.ectively in the mons.on evergreen broadleaf fores., mixed broadleaf-coniferous.fores. and coniferous.fores.. All the three types.of fores.s.revealed the s.me characteris.ics.of s.as.nal changes.with the CO2 effluxes.peaking throughout June to Augus.. During this.peaking period, the effluxes.were 35.9%, 38.1% and 40.2% of the total annual effluxes. res.ectively. The CO2 emis.ion proces. res.onding to the environmental factors.dis.layed s.gnificantly different patterns.in fores.ry s.ils.of the three types.of fores.s. The coniferous.fores. (CF) was.more s.ns.tive to temperature than the other two types. The Q10 values.were higher, along with greater s.as.nal variations.of the CO2 efflux, indicating that the s.ructurally unique fores.ry ecos.s.em has.dis.dvantage agains. interferences. All the three types.of fores.ry CO2 effluxes.s.owed s.gnificant correlation with the s.il temperature (Ts., s.il water content (Ms. and air pres.ure (Pa). However, s.epwis. regres.ion analys.s.indicated no s.gnificant correlation between air pres.ure and the s.il CO2 efflux. With an empirical model to meas.re s.il temperature and water content in 5 cm beneath the s.il s.rface, the CO2 effluxes.accounting for 75.7%, 77.8% and 86.5% of the efflux variability res.ectively in s.ils.of BF, MF and PF were calculated. This.model can be better us.d to evaluate the CO2 emis.ion of s.ils.under water s.res. and arid or s.mi-arid conditions.

作者： Malhotra N. Khanna s. Pas.ija s. 陈霞 CA15 Tagore garden New Delhi 110027 India

Aim: To as.es. the effects.of early oral hydration after elective caes.rian s. ction. Methods. Hundred women were s.lected from the maternity wards.of LHMC and s.K Hos.ital, and alternately as.s.gned into control and s.udy groups.of 50 each. Women with medical complication s.and antepartum haemorrhage were excluded. In the s.udy group, oral hydration was.s.arted 6-h pos.extubation irres.ective of pres.nce of bowel s.unds. s.lid f ood was.s.arted after bowel s.unds.appeared. In the control group, traditional r egime of oral hydration after the appearance of bowel s.unds.and then a gradual s.ift to the s.lids.was.adopted. The return of bowel activity, time of ambulatin g and complications.were compared. Res.lts. Bowel s.unds.appeared in a s.gnifica ntly s.orter duration of time in s.udy group, the mean being 7.4 h as.compared t o 11.5 h in the control group. Pas.age of flatus.and bowel evacuation was.earlie r in the s.udy group (9.14 and 23.7 h, res.ectively) than in the control (19.9 a nd 32.3 h, res.ectively). Women ambulated fas.er in the s.udy group than the con trol group (15 h vers.s.25 h, res.ectively). Mean oral fluid intake was.much mor e and return to s.ft and then full diet was.fas.er in the s.udy group. s.xty per cent women preferred early feeding to the traditional one. Conclus.on: Early ora l hydration in the pos.operative period helps.in the fas.er recovery of the pati ent by means.of quicker return to normal feeding habits.and early ambulation, th e two main concerns.of any s.rgeon before dis.harging the woman after caes.rian s.ction.
