摘要
对从19世纪中期土地生态思想萌芽以来的相关评价研究成果作了综述。在发展历程上,将土地生态评价发展总结为4个方面。在发展指标上,对不同的评价对象和目标,主要有基于FAO土地质量评价演化而来的评价指标、概念性框架评价指标和基于景观视角的评价指标,更加完备和统一的指标有待进一步探索。在评价方法上,将其归纳为数学模型法、空间模型法和景观生态模型法,逐渐体现空间格局和景观一体化格局的重要性。在东部地区资料充足的发达省份可尝试建立土地生态评价指标体系,生态情况具有特殊性的区域需更多的针对当地的生态环境情况建立专门的评价指标。
Land ecological evaluation from the perspective of ecology is the process of multiscale evaluation of land ecosystem and has been one of the hot topics of land science researches in recent years, which can not only guarantee the sustainable development of land resources and the good condition of land ecology, but also enrich theories of land resource management discipline. This paper summarizes the research achievements in land ecological evaluation since the emergence of land ecological thoughts in the mid-19th century from four aspects. The development index system is based on FAO land quality evaluation index, conceptual framework evaluation index and landscape perspective evaluation index according to different evaluation objects and objectives. The evaluation methods can be classified as mathematical model method, spatial model method and landscape ecology model method, which gradually embodies the importance of spatial pattern and landscape integration. In the case of this country, attempts can be made to build the land ecological evaluation index system in eastern provinces, where enough data are available. Specialized evaluation index is needed to establish according to the local ecosystem in the regions where the ecological condition is particular.
