摘要
农田生态系统是一个为人类提供所需食物和其他农产品生产的半人工半自然生态系统,而高原湖泊周边农田生态系统更具特殊性和典型性。本研究选取云南省抚仙湖和杞麓湖所在地的澄江市和通海县农田生态系统为研究对象,选定2大类共6项核算指标,核算出澄江市和通海县农田生态系统生态产品总值。结果显示:澄江市和通海县2021年农田生态系统生态产品总值分别为32.14亿元和42.06亿元,澄江市和通海县2021单位面积农田生态系统生态产品总值为16.77元/m^(2)和20.75元/m^(2);农田生态系统生态产品价值量主要体现在物质产品供给,其次为调节服务价值,文化服务价值较低;农田生态系统物质产品供给价值的高低与种植农作物种类关系密切,农田生态系统调节服务价值则主要与农田类型和农田位置有关。
The farmland ecosystem is a semi-artificial and semi-natural ecosystem that provides food and other agricultural products for human needs,while the farmland ecosystem around plateau lakes is more unique and typical.This study selects the farmland ecosystems of Chengjiang City and Tonghai County as the research object,where Fuxian Lake and Qilu Lake are located,and a total of six accounting indicators in two categories were selected to calculate the gross ecosystem product of farmland ecosystems in Chengjiang City and Tonghai County.The results showed that the total value of farmland ecosystem ecological products in Chengjiang City and Tonghai County in 2021 was 3.214 billion yuan and 4.206 billion yuan,respectively,and the total value of farmland ecosystem ecological products per unit area in Chengjiang City and Tonghai County in 2021 was 16.77 yuan/m^(2) and 20.75 yuan/m^(2).The value of ecological products in farmland ecosystem is mainly reflected in the supply of material products,followed by the value of regulating services,and the value of cultural services is low.The supply value of material products in farmland ecosystem is closely related to the type of crops planted,while the value of farmland ecosystem regulation service is mainly related to the type and location of farmland.
