| 摘 要： | 目的]综述中国农牧交错带研究进展。方法]从不同土地利用类型对土壤、降水及水源涵养、气候和覆被4个方面的影响出发,对我国农牧交错带热点问题的研究现状进行了总结,并对农牧交错带研究今后的发展提出了建议。结果]中国农牧交错带研究取得了较大进展,但仍不够深入和全面。建议：目前我国的农牧交错带研究应围绕怎样解决农田和草地退化这一核心问题展开深入研究;对农牧交错带研究较薄弱的方面进行多领域融合式的深入分析;将农牧交错带的研究成果充分用于生态环境的恢复、提高生产力等实际生产生活中;将农牧交错带各方面的研究归结到全国以至全球的高度上,进行各领域更加全面的延伸。结论]为我国农牧交错带的生态保护提供了参考。

| Abstract: | Objective]The study was conducted to overview the farming-pastoral ecotone research progress in China.Method]Started from the influences on soil,precipitation and water conservation,climate and mulching of different land use types,the paper summarized the current research situation on several hot issues and proposed suggestions for future study.Result]Researches on farming-pastoral ectone in China have achieved great progress,but still require more deep and comprehensive studies.Suggestions:Current studies should focus on solutions for degradation of farmland and grassland;Conduct deeper analysis on the relatively weaker aspects in a multi-domain fusion type;Implement the study results on eco-environmental recovery,production improvement and other practical activities;Lift the research of ecotone to a national or even global level,and make them far more comprehensive.Conclusion]Provide theoretical basis for ecological protection of farmingpastoral ecotone in our country. |
