Abstract:With increased population and accelerated industrialization in the world, the global climates and environments have changed greatly in past 100 years. It is well known that the stomata of plants are sensitive to climatic changes. The studies on the responses of plants to climatic changes or the reconstruction of the paleo-climates from foliar stomata parameters (stomata index and density) of plant specimens or fossils have become a highlight in the field of physio-ecology in recent years. But by now, there ...
