| 中文摘要: |
| 农业生物多样性对粮食安全、农业系统生产力及可持续性贡献极大,尤其是在未来全球气候变化加剧的背景下,多物种和种群可利用性可为不同条件下农业生产和多种生态过程提供支持,生物多样性是维持粮食安全的重要“生物保险”。黑土区生态类型多样,具有实现农业绿色发展的天然优势。然而,由于长期高强度开发利用,黑土区耕地开始退化,湿地、林地等半自然生境面积减少导致生物多样性下降,严重制约黑土区农业绿色发展。本文在分析黑土区生物多样性现状的基础上,对照借鉴国内外生物多样性保护政策现状,指出了黑土区农田生物多样性保护存在的主要问题,进而依据农田生物多样性保护的基本原则及主要目标,提出黑土区集约化农田生物多样性保护对策,以期为黑土地生物多样性复原及农业绿色转型提供理论依据。 |

| Agricultural biodiversity greatly contributes to food security, agricultural system productivity, and sustainability, especially in the context of global climate change, Multi species and population availability can provide support for agricultural production and various ecological processes under different conditions. Biodiversity is an important "Bio-insurance" for maintaining food security. The black soil area has diverse ecological types and natural advantages in achieving green agricultural development. However, due to long-term and intensive development and utilization, the cultivated land in the black soil area has begun to deteriorate, and the reduction of semi natural habitats such as wetlands and forests has led to a decrease in biodiversity, seriously restricting the green development of agriculture in the black soil area. On the basis of analyzing the current situation of biodiversity in the black soil area, and comparing the development status of biodiversity protection technology systems at home and abroad, we pointed out the main problems in the protection of farmland biodiversity in the black soil area. Then we proposes strategies for intensive farmland biodiversity protection based on the basic principles and main objectives of farmland biodiversity protection, so as to provide theoretical basis for the restoration of black soil biodiversity and the green transformation of agriculture. |
