摘要: 作为生态风险领域的重要研究主题,土地利用生态风险研究近年来热度持续上升。为考察国内土地利用生态风险的研究进展,选取该研究主题现有国内文献,通过编码、分析和归纳,从研究区域分布、数据采集与处理、土地利用分析方法、生态风险分析理论与方法几个方面进行分析,以期对土地利用生态风险研究现状做出清晰准确的概括,为后续研究提供参考。研究表明,目前的研究区域覆盖面广泛,采样对象特征呈现多样化趋势,其中西部地区占比较大,反映了学术界对西部欠发达地区生态健康的密切关注。“3S”技术作为主要的数据获取手段,为现有研究提供了详实的数据资料。根据数据进行土地利用变化分析是生态风险评估的基础,目前以描述性分析方法为主,较少使用预测模型。生态风险计算方法以国际传统生态风险评价理论和景观生态学理论为主要理论依据,其中基于后者的ERI方法可以进行深入的生态风险时空分析,近年来逐渐成为主流方法。综合来看,由于部分贫困地区数据采集技术普及程度有限,为响应和支持国家乡村振兴、精准扶贫等战略,后续可适当增加对经济欠发达农村地区和山区的研究数据获取。定量研究方式虽然能在一定程度上反映研究区域的土地利用生态风险状态,但其背后复杂的驱动因素仍需更多的研究投入,为减少评价过程中研究者主观经验的干扰,未来可适当引入不确定性分析。

Abstract: Research of ecological risks of land is becoming more popular recently. In order to study the research advances in ecological risks of land use, this paper, based on references, studies the research advances from study areas distribution, data collection and processing, land use analysis methods, ecological risks analysis theory and methods. Study areas are widely spreading with diversified sampling, of which the central and western China hold the majority, indicating the underdeveloped western China attracts more attention. “3S” technology provides lots of data. Descriptive analysis prevails, with fewer modeling. Calculation of ecological risks is based on internationally traditional ecological risk evaluation theory and scenic ecology. ERI can be used for a further temporal-spatial analysis of ecological risks and prevails. Studies on underdeveloped area are quite limited, this paper suggests boosting research in western. Quantitative study can reflect the ecological risk status of land use to some extent, but it needs more input in studying its complicated driving forces. Uncertainty analysis is suggested to be used to minimize the researchers subjective experiences in ecological risks evaluation.

Key words: land use, ecological risks, 3S technology, research advances
