摘要: 以人地关系紧张的淅川县为研究对象,采用Invest模型评估了2014年淅川县森林资源土壤保持功能。结果表明:1)土壤保持功能较好的地区主要分布于西北部,土壤保持功能较差的地区主要分布于东南部;2)森林覆盖高的区域,土壤保持功能远高于森林覆盖低的区域;3)各地类年均土壤保持量大小顺序为有林地﹥灌木林地﹥疏林地﹥苗圃地﹥未成林地。

关键词: InVEST模型, 森林资源, 土壤保持

Abstract: With Xichuan county as the research object and by using the Invest model,soil conservation function was analyzed in 2014.The results showed that:(1) the areas of better soil conservation function are mainly distributed in the northwest,and the areas of poor soil conservation function are mainly distributed in the southeast;(2) the area of higher forest cover,soil conservation function is far higher than that of low forest cover area;(3) the order of soil conservation per year from high to low is arbor forest land,shrub land,open forest land,nursery land,young forest land,and other woodland.

Key words: InVEST Model, forest resources, soil conservation
