INFLUENCE OF CLIMATE ON FORESTS AND SEED STORAGE

摘要

The appropriate management of world's vegetation resources requires understanding of their ecology including climatic relations. In view of its economic importance, forestry is an appropriate example to illustrate applied bioclimatology. The distribution and growth rates of forest species reflect climatic conditions and forest in turn affect energy and mass exchanges in the climatic systems. Individual tree species, like other plants, have optimum climatic requirements. Favourable conditions must bemet by both the regional macro and micro-climates within the forest itself. Widespread deforestation, changes in species composition or conversion of land use alter surface heat and water budget (table 1) which may in turn affect the regional meso-climates.
