Spatial and Temporal Patterns of Wetlands in Hebei Province

Abstract

Abstract Wetland is an important part of the ecosystem and important research subject in global environmental change and sustainable development. This study parents a wetland analysis of Hebei Province in China for the period from 2009 to 2017, on the basis data statistics and GIS technology. The results show that, wetland area decreased from 27.0×104 hm2 to 24.0 ×104 hm2, decreased of 3853.42 hm2 with an average annual, decreased rate 0.7%-2.4%. The structure of costal shoal, inland shoal and marshland remained at 0.36:0.60:0.04 level. The transition between wetland and other types of land were calculated by Matrix Model of Land Transfer. The results show that the wetland area mainly from cultivated land, water -water conservancy facilities land and woodland, mainly converted to urban industrial land and transportation land. The characteristics of spatial and temporal pattern change is significant. where wetlands have declined dramatically are concentrated in four areas. They are District of Bashang Plateau-Yanshan Mountain northern, District of Qin-Tang-Cang coastal city, Central plain of the province, Southwest of the province respectively.
