Invasion of alien plant species can alter local plant diversity and ecosystem processes closely linked to soil organic carbon(SOC)and nutrient *** ecosystem processes such as microbial respiration and enzyme activity have been poorly explored under alien plant invasion and especially following invasive plant species *** studied the impact of Prosopis juliflora and Acacia mearnsii invasion and subsequent removal on local plant community composition and diversity and on soil microbial respiration and enzyme activity in two biodiversity hotspots in Southern *** of Prosopis promoted recolonisation of local vegetation as indicated by a 38% and 28% increase in species richness and ground vegetation cover,respectively,compared to an unremoved *** and Acacia removal led to a significant reduction in soil microbial biomass C(MBC),respiration,dehydrogenase and urease activity due to increased microbial respiration and N mineralisation *** metabolic quotients qCO_(2) in soil at Prosopis and Acacia removed sites indicate that MBC pools declined at a faster rate than SOC,resulting decreased MBC/SOC ratios compared to their respective removed *** and undisturbed ecosystems maintain more SOC through increased belowground and aboveground C input in the soil,resulting in a higher MBC content per unit *** results indicate that the interaction between above-and below-ground communities is a critical factor determining the structure and dynamics of local plant communities,especially in ecosystems affected by plant invasions.

The man with golden hands

引用

中国周刊 2003年第11期 14-15页

作者： rainer THOMM

Lim Soo Foo is a man who can do nearly anything with his hands. Among his most artistic achievements is his collection of hand-crafted pipes that I was able to admire at a recent Cigar Club dinner. But, that is jumping the gun, so let’s go back in *** a lunch of Hainan chicken the next day, Mr Lim told me about his life. His father was born on Hainan Island, so I had inadvertently made the right choice. The best of the Hainan chicken, Mr Lim asserts, comes from Wenchang, his ancestral home. The father went to Malaya with his family while he was still young, and that is where Mr Lim Junior was born, during World War II. When the Japanese forces arrived, the family hid in the

So much more than just a few puffs of smoke

引用

中国周刊 2005年第Z1期 18-19页

作者： rainer Thomm

What’s the first thing to come to mind when thinking of Cuba? - Sugar? Rum? Caribbean beauties? - Possibly, but more likely it’s one of life’s ultimate luxuries: high-quality cigars. Imagine spending close to 300 kuai on a stick of tobacco, only to see it go up in smoke within less than an hour! Well, that’s exactly what discerning aficionados of the real thing are now able to do right here in Beijing. Gone are the days when one had to travel to Hong Kong in search of one’s favourite weed. A Habanos cigar shop was opened at the St Regis Hotel just a little while ago - and it was clear that Cubans don’t like to do things by half measures. What a party that was! Everyone who had ever heard of cigars was there - a great night to meet old

SARS without Scars

引用

中国周刊 2003年第4期 10-11页

作者： rainer Thomm

It is no secret that many foreigners have left China in recent weeks and months, panicking at the threat of SARS or, in some cases, sent home by their employers. Some of them will never return, or so they say. For those of us who have not gone away, here are the experiences of three foreign friends, and their ways coping with the threat of infection.

The green leaves of Nanjing

引用

中国周刊 2004年第3期 13-15页

作者： rainer Thomm

August 1989Hot town, summer in the city, with temperatures in the high 30s. Amazingly enough, the heat is bearable because there is plenty of shade. Nanjing is famous for the plane trees that line its streets and avenues. It’s a good thing for people like me who have little vegetation on their heads: we don’t have to worry about getting sunburnt on top.1989 being a year when nothing much is being done by way of business, I have plenty of time to travel around different parts of China. Nanjing most certainly is one of the nicer destinations among the places I am visiting. One of the most beautiful features of the city is the Zijin Shan (Purple Mountain) right in the middle of it. Few places I have been to can boast of such an attraction. Miles and miles of woodland to climb, and then

Going Like Clockwork:The Swiss-Chinese relationship

引用

中国周刊 2003年第8期 11-14页

作者： rainer Thomm

The first object one sees as one en ters the reception of the Swiss embassy in Beijing is a semi-psychedelic plastic cow with a clock attached to either side. What does it mean. the visitor wonders. Could it be an allusion to the fact that it was a Swiss company - Nestle -that played a major role in developing China’s dairy industry? Who knows? Whatever the thinking behind it, this cow certainly sets the embassy apart from any other. Cow or no cow, Switzerland is different in many respects from most other countries now represented in China. For one thing, Switzerland was a pioneer in
