退耕还林对农户非木材林产品采集的影响

The Impact of SLCP on Collection of Non-timber Forest Products

退耕还林对农户生计有着重要影响,其主要途径是改变农户生计资本组合及其配置;非木材林产品是山区农户的生计资本之一,目前鲜有针对这类活动影响的具体研究。本文遵循可持续生计分析思路,利用来自陕西秦岭山区农户的调查数据,关注不完全市场条件下,政策对不同农户影响的差异性。结果表明对不受非农市场约束的农户,这一政策能够减少非木材林产品采集的依赖度和发生率;而对于受约束农户,这种作用并不显著。

The Sloping Land Conversion Program(SLCP) is one of the largest payments for environmental service(PES) programs in the world,and this paper focuses on the different impacts of the program on collection of non-timber forest products(NTFP) using sustainable livelihood approach and household survey data from Zhouzhi County,China.Participating in the program reduces the collection of NTFP only for those households without non-farm labor supply constraints,since the program provides payments for them and free their on-farm labor as well,therefore those participants can shift labor to non-farm labor markets;while the program has not significant effect on the collection of NTFP for households unable to shift their labor to non-farm sectors due to market imperfections and poor asset endowments.
