Study On Ecological Impact Of The Land Remediation Planning In Shang Si County Based On Ecosystem Services Value

Regional land remediation will cause changes in the structure of land use, leading to all kinds of land ecological type, size, shape and spatial layout changes, and thus have significant impact on the local ecological environment.In the theory of the value of ecosystem services, based on the combination of the characteristics of regional land remediation work its land ecosystem types and when the correction value of ecosystem services before and after remediation value accounting, quantitative analysis and presentation can be induced land land remediation structural changes brought about by the use of ecological impact, and thus the lack of analysis of the current round of planning, planning for a new round of land remediation program provides recommendations for improvement.By Shang si County in2005,2010,2015three land after remediation of land use to account for the value of ecosystem services and comparative analysis, the current round of land remediation plan to make local rise in the value of ecosystem services, the local ecological have a positive impact on the environment. Among them, the various types of land ecosystem service value of the county’s contribution to the total value of the proportion of ecological changes; eight townships in the county, seven townships enhance the value of ecosystem services, a decline in the value of ecosystem services towns, land remediation after the ecological benefit communes situation will be different.After remediation plan fully into account environmental effects arising from proposed planning proposal is to vigorously develop and implement forest and afforestation work, strict protection of wetlands, to strengthen high standards of construction of basic farmland, control the excessive growth of construction land, avoid simple and extensive unused land development. Meanwhile, we should focus on land remediation work ecological and environmental protection, to take effective measures to improve land remediation ecological protection system to ensure that our land remediation planning to carry out scientific and effective, secure land ecological security and sustainable social and economic development.
