摘要:

以淅川县为研究对象,采用Invest模型评估了2004年、2009年和2014年淅川县森林资源各地类水源涵养功能。结果表明:1)淅川县西部和北部地区水源涵养功能较好,东南部地区水源涵养功能较差。2)水源涵养功能在森林覆盖高的区域明显优于森林覆盖低的区域。3)乔木林地年均水源涵养量最大,为300.51mm;其他林地水源涵养量最小,为44.83mm。森林资源各地类年均水源涵养量大小顺序为乔木林地﹥灌木林地﹥疏林地﹥未成林地﹥苗圃地﹥其他林地。

关键词: InVEST模型, 森林资源, 水源涵养

Abstract:

With xichuan county as the research object,headwater conservation function is analyzed in 2004,2009 and 2014 by using the Invest model. The results showed that:(1)The headwater conservation function is better in western and northern regions of Xichuan,and is poor in the southeast.(2)The headwater conservation of the areas with high forest cover was significantly better than that of the areas with low forest cover.(3)The highest headwater conservation amount per year is arbor forests with 300.51mm,and the lowest is other woodland with 44.83mm. The order of headwater conservation amount of forest resources per year from high to low is arbor forests,shrub land,open forest land,immature forest land,nursery land and other woodland.

Key words: InVEST model, forest resources, headwater conservation
