Maryland Ecosystem Services - Nitrogen Removal Economic Value - dollars per year
收藏资源简介:
This layer quantifies the yearly economic value of nitrogen removal in Maryland's forest and wetland areas. Economic values are based on a number of factors, including the average cost to remove nutrients using best management practices, amount of funds provided for the BMP cost share program through the state and the Bay Restoration Fund , and the price on nutrient trading markets. The averaege value is $8.36 per lb nitrogen. Urban and agricultural lands are particularly important nutrient sources, and forests and wetlands in watersheds with high incidence of these land-uses tend to have high values of the nitrogen removal service. This service totals $402.6 million for Maryland yearly. This data layer was created as part of the Maryland Department of Natural Resources "Accounting for Maryland's Ecosystem Services" program. This is a MD iMAP hosted service. Find more information on https://imap.maryland.gov.

本数据图层量化了马里兰州森林与湿地生态系统年度脱氮服务的经济价值。其价值核算基于多项核心要素:采用最佳管理实践(Best Management Practices,BMP)脱除营养物质的平均成本、州级及海湾修复基金(Bay Restoration Fund)为BMP成本分摊项目拨付的资金总额,以及营养物质交易市场的交易价格。每脱除1磅氮的平均经济价值为8.36美元。城市与农业用地是流域内主要的营养物质来源,在这类土地利用占比偏高的流域中,森林与湿地的脱氮服务价值通常更高。该脱氮服务每年为马里兰州带来的总经济价值达4.026亿美元。本数据图层为马里兰州自然资源部“马里兰州生态系统服务核算”项目的产出成果,由马里兰州iMAP(MD iMAP)托管运营。更多相关信息可访问:https://imap.maryland.gov。地图服务链接:https://mdgeodata.md.gov/imap/rest/services/Environment/MD_EcosystemServices/MapServer/17。生态系统服务图层下载地址:https://downloads.mdgeodata.md.gov/Environment%20Downloads/Ecosystem%20Services/EcosystemServices.gdb.zip
