走在千年瓷都

景德镇珍贵的陶瓷古迹、精湛的制瓷技艺构成了她独具一格的旅游文化.曾经两次路经景德镇,但都匆忙而过.前不久,我第三次来到景德镇,一天一夜,驻足留连,终于圆了心中一个愿望--不仅是领略了千年瓷都的自然历史文化,更多的是有机会亲近千年古镶留下的历代官窑、民窑遗址和无数散布于城内古街区古弄巷中的各式古建筑群落.     

清明上河图中的空间地理

《清明上河图》中描述的熙熙攘攘的滨水商业居住空间,向人们展示了令人神往而独具特色的滨水生活。它不仅有朴素的生态思想,而且还有滨水空间公共开放的特征和独特的历史、文化特色,对现代城市滨水商业居住空间的景观规划设计有非常重要的启发和借鉴意义。

广西红树林湿地资源非使用价值评估

采用条件价值法,通过支付意愿调查,对广西红树林湿地的非使用价值进行了评估.结果表明,广西红树林的非使用价值为37.61亿元,其中存在价值16.66亿元;遗产价值10.94亿元;选择价值10.00亿元.广西红树林人均支付意愿值为50元.总支付意愿率为59.2%;除年龄与支付意愿无关外,性别、职业、文化程度、技术职称、收入水平、了解程度、偏爱程度等都与支付意愿呈极显著相关关系;性别与WTP值相关,但不显著,而其他因素与WTP值呈现极显著相关.     

A culture-dependent survey of thermophilic bacteria from hot springs in Xiamen area in China

Microbes are believed to play important roles in ecosystem function in many environments. The hot springs of Xiamen Island are close to the Xiamen Sea, and may have some characteristics different from those of inland hot springs. Microbes living in the hot springs of Xiamen may have new characteristics. However, little is known about microbial communities of hot springs close to the Xiamen Sea. A culturedependent survey of microbial population in the Xiamen hot springs was performed by using an approach combining total cellular protein profile identification and 16S rRNA gene sequencing. A total of 328 isolates of bacteria were obtained from liquid and sediment samples from the Xiamen hot springs, including neutrophilic thermophilic bacteria and moderately thermophilic acidophiles. Neutrophilic thermophilic bacteria, which grow at a temperature range of 55—90℃ including Rhodothermus marinus (Strain 1), Thermus thermophilus (Strain 2), Thermus thiopara (Strain 3), Geobacillus stearothermophilus (Strain 4), Geobacillus thermoleovorans (Strain 5), and Pseudomonas pseudoalcaligenes (Strain 6), were recovered by 2216E plates. Moderately thermophilic acidophiles, which can grow at temperatures above 50℃ and a pH range of 1.8—3.5 such as Alicyclobacillus acidoterrestris (Strain 8), Sulfobacillus acidophilus (Strain 9), and Sulfobacillus thermosulfidooxidans (Strain 10), were isolated on selective solid medium containing sulfur and Fe2+. Among these strains, Rhodothermus marinus, Thermus thermophilus and Geobacillus stearothermophilus are not only thermophiles, but also halophiles. One bacterium strain (Strain 6) shared 99% nucleotide sequence homology with Pseudomonas pseudoalcaligenes on the 16S rRNA gene sequence, but was quite different from Pseudomonas pseudoalcaligenes in biological characteristics, suggesting that it may represent a novel thermophilic species. Results indicated that various species of neutrophilic thermophiles and moderately thermophilic acidophiles were widely distributed in the Xiamen hot springs and that Rhodothermus marinus and Thermus thermophilus dominated the cultivable microbial community.
