摘要/Abstract

摘要： 以科尔沁沙地长期封育草地的19种植物为对象，分别测定植物高度（Height）、比叶面积（SLA）、叶片干物质含量（LDMC）、碳含量（LNC）、氮含量（LNN）5个植物功能性状，比较不同生活型（一二年生植物、多年生植物）和功能型（C₃植物、C₄植物）植物功能性状的差异性，探讨沙地内典型草地不同植物功能性状的内在联系及其对环境的适应性。结果表明：多年生植物的LDMC极显著大于一二年生植物，且C₃植物的高度显著大于C₄植物；对于一二年生植物而言，C₃植物的LNC显著大于C₄植物；对于C₄植物而言，多年生植物的LDMC和LNC显著大于一二年生植物。植物功能性状相关分析表明，SLA与LDMC极显著负相关，LNC与LNN极显著正相关。科尔沁沙地长期封育草地植物不同生活型、功能型的功能性状存在明显差异，多年生C₄植物具有较强的生态适应能力。

Abstract: Base on the nineteen dominant species in Horqin sandy land under enclosure, five functional traits of height (Height), specific leaf area (SLA), leaf dry matter content (LDMC), leaf carbon content (LNC) and leaf nitrogen content (LNN) were measured. The functional traits differ in two kinds of life forms (annual/biennial plants, perennial plants) and two kinds of photosynthetic pathways (C₃ plants and C₄ plants). We compared and analyzed the discrepancy in functional traits between different life forms and photosynthetic. Furthermore, the inter relationship of functional traits and their adaptability to the environment in typical grassland were discussed. The results showed that the LDMC of perennial plants was significantly higher than that of annual/biennial plants. Regarding to the perennial plants, the Height of C₃ plants was significantly higher than that of the C₄ plants. For the annual/biennial plants, the LNC of C₃plants was significantly higher than that of the C₄ plants. Relative to the C₄ plants, the LDMC and LNC of the perennial plants were significantly higher than that of the annual/biennial plants. Correlation analyses showed that SLA and LDMC were extremely significantly negatively correlated, while, LNC and LNN were extremely significantly positive correlated. Based on the above results, we concluded the following conclusion: there are obvious discrepancy in the plant functional traits between different life forms and photosynthetic in enclosure grassland ecosystem. Perennial C₄ plants have stronger adaptability to drought environment.
