摘要
运用生态系统服务价值法的最新研究成果和GIS叠图法对江苏省扬州市新一轮土地利用总体规划进行了环境影响评价。研究结果表明,扬州市的生态服务价值在规划期内呈现先下降后上升的趋势,其中市辖区和宝应县生态服务价值呈现下降趋势,仪征市、高邮市和江都市生态服务价值在规划期内不断上升;绝大多数规划建设用地分布在非敏感区和低度敏感区,3.62%的建设用地分布在中度敏感区,0.36%的建设用地分布在高度敏感区,说明规划方案中建设用地布局具有较好的生态适宜性。针对规划实施可能产生的不良环境影响,提出切实可行的预防或减缓措施。在严格实施规划,并确保相关的环境影响减缓措施得以落实的前提下,该规划从环境保护和可持续发展的角度分析是可行的。研究表明,利用生态系统服务价值法和GIS叠图法对土地利用总体规划进行环境影响评价具有一定的科学性与可行性。
This paper used the latest research results of ecosystem services value method and map overlay of GIS method to assess environmental impact of new general land use planning of Yangzhou City. The research results indicated that ecological services value of Yangzhou City ascended after a short period of declining during the planning period, while the municipal district and Baoying County presented a descending trend. Ecological services value of Yizheng, Gaoyou and Jiangdu City presented a consistent ascending trend; Most planned constructive land was distributed in non-sensitive and low-sensitive areas, and 3.62% constructive land was distributed in middle-sensitive areas, and only 0.36% constructive land was distributed in high-sen- sitive areas, so the distribution of constructive land in the plan scheme had relatively good ecological suitabil- ity. This paper put forward feasible preventive and alleviative measures aiming at minimizing the negative im- pacts which may be caused by the implementation of the plan. In the context of strict implementation of the plan and the carrying out of relative preventive and alleviative measures, this plan is feasible from the per- spective of environmental protection and sustainable development. Using ecosystem services value method and map overlap of GIS method to assess environmental impacts of general land use planning is scientific and feasible.
