设施农用地扩张的环境效应研究进展

Research Progress on Environment Effects of the Expansion of Facility Agricultural Land

设施农用地是高强度土地利用模式的典型代表,持续、单一、集约的土地利用方式所带来的负面效应对周围环境产生了明显影响。该研究从水环境、土壤环境、区域气候等3个方面对设施农用地扩张带来的环境效应研究成果进行了总结。指出了目前该领域研究的不足:对设施农用地扩张的环境效应研究重视不够,研究成果分散、研究视角单一,缺少综合性研究。今后应加强研究设施农用地扩张的水文水环境效应研究;在土壤环境效应研究方面,应提高采样的深度,分析设施农用地长期使用所引发的土壤环境风险,分析设施农用地内部不同用地方式和类型所引起的土壤养分和金属离子的时空分布特征;加强设施农用地扩张对区域气候的影响研究,重点加强设施农用地的增温效应研究。

The facility agricultural land use is a typical representative of highly intensive ]and use pattern and is proved to have negative effects on the local environment. The major achievements and progresses in the research on the water, soil and regional climate effects resulted from the facility agricultural lands＇ expansion were summarized. Finally, possible problems and future research issues were discussed. The re- search should be strengthened on hydrology water environmental effect of facility agricultural land expansion, soil environment risk by long- term use of facility agricultural land, spatial-temporal distribution characteristics of soil nutrients and metal ions caused by different land use ways and types of facility agricultural land, effects on local climate and calefaction.
