重点生态功能区建设对海南中部山区水源涵养功能的影响
Impact of Important Ecological Areas Establishment on Water Conservation in Central Hainan Mountain Area
摘要
Abstract
Focusing on the key ecological functional areas of central Hainan (Hainan EIA) as the research area,by InVEST modelling,the water conservation function and spatial differentiation characteristics of ecosystem in 1998,2005 and 2013 were quantitatively evaluated,and the changes of water conservation function before and after construction in central mountainous area were evaluated.The results showed:①Conserving water in the area slowly decreased.The total water conservation of the middle mountain areas in 1998,2005 and 2013 was 5.693 billion,5.968 billion,5.625 billion m3,respectively.②Through years of protection and construction,Hainan EIA strengthened flood control.The total water yield of the middle mountain areas in 1998,2005 and 2013 was 9.730 billion,9.760 billion,9.350 billion m3,respectively.Throughout the three years,the amount of water produced in Hainan EIA has been relatively lower in 2013 than it was in 1998 and 2005 which showed a better flood control.Changhuajiang River basin contributed the most followed by Wanquanhe River basin.The amount of water produced from east to west gradually decreased.③Since 2005,Hainan EIA has been established,natural forest in these areas has gradually increased and the flood control of the ecosystem has been greatly strengthened.关键词
