南极普里兹湾营养盐消耗及新生产力的估算

研究了ＣＨＩＮＡＲＥ－６和ＣＨＩＮＡＲＥ－９普里兹湾内营养盐的分布及变化,采用化学质量平衡方法估计了该海区新生产力的大小。结果表明在ＣＨＩＮＡＲＥ－６期间,ＮＯ３－Ｎ、ＰＯ４－Ｐ、ＳｉＯ３－Ｓｉ消耗分别为１０６４．８、６９．２、２１９６．９ｍｍｏｌ／ｍ２,ＮＰ、ＳｉＰ吸收比分别为１５．３、３１．７,平均新生产力为９９２．４ｍｇＣ／（ｍ２ｄ）。在ＣＨＩＮＡＲＥ－９期间,ＮＯ３－Ｎ、ＰＯ４－Ｐ消耗分别为５５１．９、４１．２ｍｍｏｌ／ｍ２,ＮＰ吸收比为１３．４,平均新生产力３９０．１ｍｇＣ／（ｍ２ｄ）,表现出很大的季节和／或年际变化。估算的新生产力值都大于１４Ｃ测定的初级生产力值,表明普里兹湾海区夏季有很大的新生产力。元素吸收比和外海测定值不同,表明营养盐的吸收和循环在南极海区有很大的区域差异性。

青藏高原4月—10月光合有效量子值的气候学计算

根据１９９４年４月～１０月青藏高原太阳分光辐射的实测资料，计算出太阳总辐射中，光合有效辐射（ＰＡＲ）所占比例η＝０．４３９±０．００９，ＰＡＲ每１Ｊ的能量含有４．４３μｍｏｌ的量子。在青藏高原的气候学计算中，可用下式估算旬平均的ＰＡＲ能量日总量ＨＰＡＲ（ＭＪ·ｍ－２ｄ－１）和量子日总量ＵＰＡＲ（ｍｏｌ·ｍ－２ｄ－１）：ＨＰＡＲ＝（０．３９９＋０．０３６ｌｇＥ＊）ＨＵＰＡＲ＝（１．７６８＋０．１５９ｌｇＥ＊）Ｈ式中Ｈ（ＭＪ·ｍ－２ｄ－１）为总辐射旬平均日总量，Ｅ＊＝Ｅ·Ｐ０／Ｐ，Ｐ０（ｈｐａ）为标准大气压，Ｐ（ｈｐａ）为测点大气压，Ｅ（ｈｐａ）为地面水汽压。

Assessment of GIAHS in Shizuoka: The Traditional Tea-grass Integrated System

<正>1 Introduction In 2013,Chagusaba,which is traditional tea-grass integrated system in Shizuoka,were accepted as new world heritage site of agriculture.Shizuoka prefecture occupies a variety of elevations,from 0 to 3000m or more above sea level.Because of the diversity of land features and climates,this area produces 167 agricultural commodities.In addition,a lot of traditional agriculture and over200 local native varieties of crops have been conserved in Shizuoka

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
