青藏高原4月—10月光合有效量子值的气候学计算   总被引:4,自引:0,他引:4  
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。  相似文献

本文对南极磷虾复眼的直径与磷虾体长之间的关系、在负生长状态下磷虾复眼直径的变化等进行了研究。实验结果表明:在正常情况下(磷虾身体不出现负生长),磷虾复眼的直径与体长之间存在指数函数关系。雌性磷虾的眼径(ED)与体长(BL)之间的关系为:ED=0.5898e0.0282BL(r=0.9613,n=2419);雄虾的眼径与体长之间的关系为:ED=0.544e0.0309BL(r=0.9622,n=1920)。在相同体长的情况下,雄性磷虾的复眼直径比雌虾的大。从活体培养的结果来看,当南极磷虾出现负生长时,复眼直径保持不变,即眼径不受负生长的影响。在正常情况下(不存在负生长),雌虾的体长与眼径之间的比率(BL/ED)平均为21.32±0.04(n=1347),雄虾的体长与眼径之间的比率平均为20.68±0.07(n=748),未成体虾的体长与复眼直径之间的比率平均为21.54±0.06(n=1072)。利用体长与眼径之间的比率可以准确地将在实验室内活体培养后已存在负生长的磷虾与其它处于正常状态的磷虾分开。体长与眼径之间的比率也可以作为磷虾种群是否存在负生长的监测指标  相似文献

乌兰布和沙漠东北边缘植物群落物种多样性及其生态环境   总被引:7,自引:3,他引:7  
王君厚  任培政 《中国沙漠》1996,16(3):258-265
应用群落多样性指数(D)、均匀度(J)、生态优势度(C)等指标,对乌兰布和沙漠东北边缘不同生境(荒漠区、绿洲外围、绿洲内)的天然植物群落进行了研究,结果表明这三种指标值能有效地表征群落的组成结构特征及生境的优劣;荒漠植物群落多样性指数(D=0.603~2.984)和均匀度(J=0.337~0.691)都较低,而生态优势度(C=0.724~0.195)较高,说明荒漠植被生态环境的脆弱性,群落结构越复杂,多样性指数越高;多样性与生态环境关系密切,D和J随生境渐好而递增,C随生境渐好而递减,可作为环境评价指标;多样性在一定程度上体现了群落的发展阶段和稳定程度,越接近顶级阶段,多样性越高,且环境的改善有助于群落演替进程的加速;干旱区弃耕撩荒地次生演替植被,在弃耕初期多样性随弃耕年限增大而减小,后期处于一个较稳定的水平,且各演替阶段植物组成变化较大。  相似文献

不同激素对沙冬青组织培养生芽的影响   总被引:5,自引:0,他引:5  
蒋志荣  安力 《中国沙漠》1997,17(2):209-211
以沙冬青无菌苗茎段为材料,采用MS基本培养基,对6-BA、KT、IBA、GA进行不同浓度和不同配比试验,结果表明:6-BA(1.0mg/L)对芽的分化有利,但不利于芽的伸长生长;KT(0.1mg/L)配合IBA(0.1mg/L)既有利于芽的分化,又可增加芽的伸长生长;GA(1.0mg/L)对芽的伸长生长效果显著。  相似文献

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.  相似文献
