人类已经改变了大部分自然土地覆盖，导致全球生态系统退化和生物多样性丧失。许多国家实施了农用地转化保护付费计划，以应对这一趋势。然而，由于停止付款后土地利用的不确定性，这些计划的生态系统服务的可持续性尚不清楚。我们研究了中国退耕还林工程（GTGP）项目后在卧龙大熊猫自然保护区的土地利用计划，这是世界上最大的生态系统服务付费项目之一。尽管保护区内的农民计划在停止付款后仅将 22.6% 的 GTGP 土地重新用于农业，但这些 GTGP 地块分布在整个景观中，可能对许多生态系统服务很重要。考虑到地区差异，被调查者的年龄和家庭非农收入显着减少了计划收回的GTGP土地数量，而家庭劳动力数量和家庭已参加GTGP的土地总量则显着增加了GTGP土地家庭的数量。因此，应考虑区域、人口和经济因素，以更有效地维持生态系统服务项目付费带来的保护效益。 (C) 2009 Elsevier Ltd. 保留所有权利。
Humans have altered much of the natural land cover, resulting in ecosystem degradation and biodiversity loss worldwide. Many countries have implemented conservation payment programs for agricultural land conversion to counter this trend. However, the sustainability of ecosystem services from these programs is unknown due to uncertainty about land uses when payments cease. We studied post-program land use plans for China's Grain-to-Green Program (GTGP), one of the world's largest ecosystem service payment programs, in Wolong Nature Reserve for giant pandas. Although farmers in the reserve planned to reconvert only 22.6% of the land that was enrolled in the GTGP to agriculture after payments cease, these GTGP plots are distributed across the landscape and may be important for many ecosystem services. Along with regional differences, the amount of GTGP land households planned to reconvert was significantly reduced by the respondent's age and off-farm household income and was significantly increased by the number of household laborers and total amount of land the household had enrolled in the GTGP. Thus, regional, demographic and economic factors should be considered to more efficiently sustain conservation benefits from payment for ecosystem service programs. (C) 2009 Elsevier Ltd.
