锡林郭勒天然草原植被生产力与降水因子耦合关系研究

摘要

Growth of natural forage grass and yield closely related to the precipitation factors.Under different precipitation condition,vegetation＇s growth condition was different.Through typical investigation study and fixed-point experlment,promulgated the natural pasture vegetation to the precipitation response relation,studied the natural prairie vegetation productivity and the precipitation correlativity,provided basis for the prairie. restores.%天然牧草生长发育和产量形成与降水因子关系密切，不同降水量条件下，植被的生长状况不同。通过典型调研与定点试验．揭示了天然草原植被对降水量的响应关系，研究天然草原植被生产力与降水量的耦合性，为草原恢复提供依据。
