主要研究方向

1、 杜鹃资源收集与保育建立了杜鹃属植物功能性状、分布、气候、土壤、群落数据库;采用数量生态学方法,分析杜鹃属植物功能性状、分布与环境的关系。收集适于低海拔环境的杜鹃野生种8个,培育小苗20000余株;展示杜鹃野生种289个,温室内保育其它杜鹃野生种113个。

2、 干旱区植物群落结构、功能观察与模拟长期野外观察数据与群落生长机理模型相结合,模拟植物群落土壤植物系统的水分平衡、蒸发动力、湿度系数、热力动力、光能转换等过程,分析植物群落结构与功能动态。中国干旱区绝大部分地区湿度系数k值小于0.35×10–2,叶片投影盖度FPC小于50%,ANPP小于 1 tons ha–1yr–1。这些参数为确定干旱区恢复植被盖度及合理放牧密度提供了可靠的基础,具有较高的应用价值。

3、 半旱区植物对沙生环境的适应机制研究了籽蒿、油蒿、羊柴、柠条等优势物种对沙生环境的适应机制。不同水分利用效率是植物适应不同沙生环境的重要原因。柠条水分利用效率最高,油蒿次之,其次是羊柴、籽蒿最低;水分利用效率随供水增加及温度升高而降低。温度升高及CO2浓度倍增不利于籽蒿与油蒿的生长,而相对有利于柠条及羊柴的生长。柠条与油蒿的组合使用有利于沙生环境退化植被的恢复。
