卧龙竹类非结构性碳水化合物与叶氮含量对海拔的响应

, 2010
山地由于海拔变化导致的环境因子显著差异,成为研究植物环境适应性及其对全球气候变化响应的理想区域。以卧龙自然保护区内油竹子(Fargesia angustissima Yi)与华西箭竹(Fargesia nitida(Mitford)Keng f.ex Yi)为对象,沿海拔梯度研究了两种竹子在各自海拔分布区间内组织非结构性碳水化合物(NSC)含量、比叶面积(SLA)、以及基于单位叶面积和单位叶质量的叶氮含量(Narea,Nmass)。除油竹子叶NSC,Narea和华西箭竹Nmass随海拔升高不发生变化外 ...

中国近海温跃层判定方法的研究

, 2007
根据东海以及南海东北部多组资料,探讨了拟阶梯函数法和垂向梯度法在浅海区(水深200 m)的应用情况,分析了温跃层在陆架坡折海域的水平衔接问题.对比分析表明:在浅海区,两种方法结果比较一致,特别对某些垂直温度梯度较弱的曲线,拟阶梯函数法和实际水文廓线符合更好.陆架坡折海域,垂向梯度法对于温度梯度相对较弱的跃层刻画不好,而拟阶梯函数法可以对较弱温跃层进行判定,与实际垂直水文结构一致.深水开阔区域,垂向梯度法所得温跃层特征量与实际符合较好,而拟阶梯函数法获得的温跃层强度偏大.因此,对本研究海域来说,当水深 ...
