Abstract:

Background & Aims: In the face of a series of challenges such as climate change, population growth and agricultural intensification, how to promote sustainable agricultural development and ensure food security, agroecosystem diversity with its unique genetic, ecological and traditional socio-cultural values become an important way to solve this challenge. A comprehensive understanding of the characteristics of agroecosystem diversity, the main influencing factors, conservation and utilization measures and research tools will be an important reference for the developing of agrobiodiversity conservation strategies.

Method: This paper only focused on agrobiodiversity on farming system not broad agriculture. We systematically analyzed the impact of various influencing factors and management measures on agroecosystem diversity, introduced the current situation and changing dynamics of typical ecological regions of agrobiodiversity in China, systematically described the assessment methods of agroecosystem diversity, analyzed the conservation and management of agroecosystem diversity, and accordingly pointed out the main problems of current agrobiodiversity research in China and future prospects.

Results: The analysis shows that agroecosystem diversity plays an important role in maintaining agroecological services, improving the resilience of agroecosystems, reducing chemical fertilizer and pesticide and developing green agriculture.

Prospect: There is a need to improve agroecosystem diversity assessment indicators, strengthen agroecosystem diversity management policies and coordination mechanisms, and intensify agroecosystem diversity conservation and use, so that agrobiodiversity conservation and utilization can be mainstreamed in sustainable agriculture development.

Key words: biodiversity of agricultural ecosystem, green agricultural development, ecosystem biodiversity assessment, InVEST model, agrobiodiversity conservation
