Strategies to increase carbon fixation and sequestration by karst-adaptable plants
摘要
Abstract
Based on the analysis on the soil chemical properties in karst area, it is proved the factors that restrict the increasing of carbon fixation and sequestration by the karst-adaptable plants involve karst drought, low nutrient, high Ph value and high concentration of bicarbonate. The differences in the use of inorganic carbon and nitrogen as well as in responds to low nutrient by karst-adaptable and karst-inadaptable plants are also analyzed in the paper. The strategies to increase carbon fixation and sequestration by karst-adaptable plants are put forth, which includes the following strategies - efficiently using of bicarbonate source; gaining photosynthetic carbon fixation with low nutrition cost; absorbing restrictive ammonium nitrogen rapaciously and absorbing nitrate nitrogen as compensation. The ways to increase carbon fixation and sequestration by karst-adaptable plants is also proposed, that will maximally excavate the potential of increasing carbon fixation and sequestration by the plants in karst area.关键词
