| 摘 要： | 基于"压力-状态-响应(Press-State-Response,PSR)"模式的土地质量指标体系是国际土地科学研究的热点问题。我国经济的快速增长和土地退化的严峻形势要求建立能够衡量土地质量变化的指标体系。介绍了基于PSR框架的土地质量指标体系的来源、基本概念、评价框架和研究计划。介绍了国际土地质量指标研究计划中提出的养分平衡、产量差额、农业土地利用强度与利用多样性、土地覆被、土壤质量、土地退化、农业生物多样性、水质量、林地质量、牧草地质量、土地污染等11项土地质量指标。在总结、分析国内外土地质量指标体系研究的最新进展和研究不足基础上,提出未来我国有关部门在土地质量方面的研究趋势与建议。 |

| Abstract: | Land quality indicators based on "press-state-response (PSR)" framework is one of the present hot-spots in land science. Fast economic growth and land degradation in China urge government and scientists to build up the indicators to monitor and evaluate land quality changes. This paper introduced the origin, concept, research plan and evaluation framework for land quality based on PSR framework, and it also summarized the new progresses in the field of international land quality indicators research. In land quality indicators project, 11 land quality indicators were proposed, which are nutrient balance, yield gap, agricultural land use intensity and land use diversity, land cover, soil quality, land degradation, agro-biodiversity, water quality, forest land quality, rangeland quality, and land contamination/pollution. Some research trends and suggestions in Chinain future were also proposed. As the national agency of land management, the Ministry of Land and Resources can make contributions to land science by the application of land quality project. |
