The Chinese government adopted six ecological restoration programs to improve its natural environments. Although these programs have proven successful in improving local environments, some studies hav
Little information is available on biogenic elements(carbon, nitrogen, phosphorus and sulfur) and the ecological stoichiometric characteristics of plants in coastal wetlands. To investigate the conten
Reclamation is one of the fastest-growing land use type developed in coastal areas and has caused degradation and loss of coastal wetlands as well as serious environmental problems. This paper was aim
Extreme seasonal water level fluctuations characterize natural floodplain lakes in monsoon regions, which are crucial for ensuring lake water security, including flood prevention water supply and heal
Urban forest soil infiltration, affected by various factors, is closely related with surface runoff. This paper studied the effect of urban forest types, vegetation configuration and soil properties o
多角度偏振成像仪(DPC)是一种多角度、多光谱具备偏振测量功能的大视场偏振遥感器。偏振定标光源的发散角与DPC像元对应的视场角匹配一致,是提升DPC实验室偏振定标精度的关键因素之一。通过比较实验室偏振定标与在轨定标的状态差异,参考DPC在轨运行光学系统的成像原理,通过微分运算方式,建立一种偏振定标光源的发散角与单像元视场角匹配的模型,分析结果给出了光源的发散角应大于0.14°才能满足DPC全视场的
