Analysis of spatiotemporal variation characteristics of farmland ecosystem service values in Shandong Province,China
摘要
Abstract
To clarify spatiotemporal changes in the farmland ecosystem service values in Shandong Province,China,an ecological economics evaluation method was used to quantitatively calculate 17 farmland ecosystem service values(including 13 positive services and 4 negative services)provincially and in 16 prefecture-level cities from 2000 to 2020.During this period,the total farmland ecosystem service values in Shandong Province showed a fluctuating growth trend,and the service value provided by farmland ecosystems gradually increased.Supply and regulation services were the most important service functions,contributing a total of 83.39%to 86.72%.Other support services,social security services,and cultural services contributed<20%.The negative service value displayed a decreasing trend of fluctuation.From a spatial perspective,the Weifang,Heze,Dezhou,Liaocheng,Jining,and Linyi plain areas surrounding the central and southern mountainous areas of Shandong ranked among the top in terms of total farmland ecosystem service values,representing nearly two-thirds of the province.The total farmland ecosystem service values of Weihai,Dongying,Rizhao,Zibo,Yantai,Binzhou,and Zaozhuang ranked last,representing<20%of the province.In terms of the total farmland ecosystem service values per unit area,Zaozhuang and Tai'an consistently ranked first and second,respectively,in the province.In addition,the negative service value of the farmland ecosystem per unit area in Zaozhuang consistently ranked first in the province.The findings support the view that construction of agricultural infrastructure should be accelerated and the ecological environment improved,while reasonably developing agricultural production according to the natural conditions of different regions,adopting scientific planting techniques and efficient management methods,improving agricultural production efficiency,and continuously enhancing the various farmland ecosystem service values.关键词
