11、61.Research advances in service functions of farmland ecosystems: a review Liu Mingda, Huang Xiaoshan, Zhang Yulong, Cui JianguoCollege of Land and Environmental science, Shenyang Agricultural University, Liaoning, Shenyang 110161, China Abstract: Farmland ecosystems are the foundation of human soci
12、etys existence and development. The research on service functions of farmland ecosystems and their valuation is of great significance. This paper reviewed the valuation and characteristics of service functions of farmland ecosystems, and classified their service functions as product supplying, ecolo
13、gical regulating and cultural edu-cating (life ensuring). Then the paper analysed the problems in todays research. For example, the research on formation mechanism of farmland ecosystem services and its parameters is scanty, the valuation is inaccurate, the indicators and methods need to be im-prove
14、d, etc. Therefore the future research on valuation of service functions of farmland ecosystems should be focused on theory ex-ploration and research method improvement, commencing with the microcosmic formation mechanism to carry out valuation re-search on different scales and types of farmland ecos
15、ystems. By considering sufficiently the factors influencing its function value, improve the means, method and technique of evaluation to make the results more comparative and practicable, and supply bases for utilizing agricultural resources, managing farmland ecosystems reasonably and developing agriculture sustainably. Key words: farmland ecosystem; service function; valuation
