光阴的筵席

朝来暮去,清晨与黄昏是这筵席的常客。黎明前的黑暗里,仿佛有什么东西悄悄地钻了出来,一切都在慢慢的改变着。野草丛中开始有虫鸣窸窣,不经意间还有三两声鸟鸣,树枝沙沙作响。黑暗是生灵的狂欢,参差不齐的声音响起,就这样伴着野草和大树的舞姿开始了它们的狂欢。渐渐的,柔和的白光轻纱似地落下来,缓缓地,似带着些困倦,似还在它的梦中流连。万仗霞光霎时从云层倾泄,新的一天就这样到来。

Potential effects of future adoption of the REDD mechanism as a preventive measure against deforestation and forest degradation in North Korea

This study assesses potential effects of adaption to climate change in the future as a carbon related value using a baseline and credit approach, considering the implementation of the Reducing Emissions from Deforestation and forest Degradation （REDD） mechanism. Basic data were obtained for implementing the REDD mechanism in the Democratic People＇s Republic of Korea （DPRK） for scientific decision-making to prevent deforestation and forest degradation. The potential effects according to the implementation of the REDD mechanism in the DPRK based on forest status data （the latest） are as follows. If the deforestation rate is reduced to a level below 6% through a 20-year REDD mechanism beginning in 2011, 0.01-11.64 C-tons of carbon credit per ha could be issued for DPRK. Converted into C02-tons per ha, this amounts to 0.03-42.68 C02-tons, which translates to a minimum of 226,000 CO2-tons and a maximum of 289,082,000 C02-tons overall for forests in DPRK. In terms of carbon price, this measures up to 1.1o million USD- 1.4 billion USD, considering that the REDD carbon price in voluntary carbon markets in 2010 was around 5 USD.

大街,见不着你身着制服威风凛凛的英姿,法庭,听不到你义正词严痛斥罪孽的声音。干警花名册有你的职务姓名,小小铅字盘是你的用武之地。日出月落,朝来暮去,蜡纸、油墨,油墨、蜡纸;春夏秋冬,周而复始,

烟雨楼台凤凰山——宋画里的生活

“东南形胜,三吴都会,钱塘自古繁华。”柳永这一阕《望海潮》,说的是北宋时期的杭州胜景。相传,金国海陵王完颜亮见此词中杭州风华,才起了南下侵宋之意,最终丧国殒身。北宋时杭州繁华如此,可以想见南宋时作为都城,杭州更该何其繁华。朝来暮去,时光流逝。时至今日,我们穿梭在这座历史文化名城,寻找那些散落各处的南宋遗存,用考古还原遗址原貌,从宋画中探寻昔日皇城的万千风韵。
