摘要：在中国东部沿海地区沿纬度梯度选取8个水杉林,研究水杉的叶片长度、叶片宽度、叶片周长、叶片面积、叶片长宽比、比叶面积、叶片干质量等叶片性状指标的纬度变化规律,分析叶片性状与气象、土壤因子的关系.结果表明:随着纬度的升高,水杉叶片长、宽、周长逐渐增大,叶面积和比叶面积先增加后降低.在纬度梯度上,水杉叶片性状的变化主要受年均温和年均降水量的影响.随着土壤氮含量的增加,比叶面积呈先下降后上升的趋势,叶干质量则呈显著下降的趋势;随着土壤磷含量的增加,比叶面积逐渐增加,而叶干质量则显著下降.
We analyzed the rules of Metasequoia length, leaf width, leaf perimeter, leaf area, glyptostroboides along with latitude, including leaf ratio of leaf length to width, specific leaf area （ SLA）, and leaf dry mass based on eight stands growing at different latitudes in the coastal area of eastern China, as well as their relationships with climatic and soil factors. The results showed that the leaf length, leaf width and leaf perimeter increased with increasing latitude, while the leaf area and SLA firstly increased and then decreased. The mean annual temperature and annual precipitation were the major environmental factors affecting the leaf traits along latitude gradient. With the increase of soil N content, the SLA decreased firstly and then increased, while the leaf mass decreased significantly. With the increase of soil P content, the SLA increased, and the leaf mass decreased significantly.
