Abstract:
Taking 36 main garden plants in Suzhou Lingering Garden as experimental materials,leaf traits indexes of plants with different life forms were analyzed and determined by leaf area scanner，Kjeldahl nitrogen analyzer and other experimental instruments and statistical analysis methods.The variation characteristics of leaf traits of 36 different life-form plants in Lingering Garden and their trade-off strategies in functional structure were studied,in order to provide reference for species selection of regional ecological restoration.The results showed that the coefficient of variation of plant leaf traits in the study was from 32.54% to 116.08%，the variation coefficient of SLA was the largest，while that of LDMC was the smallest.Among the main leaf traits，there were significant negative correlation between LT，LTD，LDMC，Nareaand SLA(P＜0.01).The leaf traits of plants varied widely，and the differences of different life forms plants were significant.Herbs and lianas in life form were located in the fast investment-returning species with high SLA，low LDMC，and high Nmass，while shrubs and arbors were located in the slow investment-returning species with low SLA，high LDMC，and low Nmass.
