【摘要】：基于地理国情监测地表覆盖矢量化数据,运用修正的生态服务价值评估模型,以伊春市为研究实例开展了生态系统服务价值评估,并分析了其与社会经济发展的关系。结果表明:2015年伊春市各生态系统提供的生态服务价值总量为2.62×107万元,森林提供的生态系统服务价值最高,占总价值的91.60%,其次为水域,草地次之,分别占5.23%和2.00%。生态服务价值空间格局分布并未表现明显的规律性。虽然伊春市是黑龙江省生态系统服务价值高产值区,但是生态系统服务价值总量、均值及人均占有量在各辖政区内分布极不均衡,且与社会经济发展不协调。根据各辖区的资源和环境状况,确定科学的产业结构,促进当地生态环境与经济建设的协调发展仍是当前的要务。
[Abstract]:Based on the geographical conditions to monitor the vectorization of the surface coverage, the revised ecological service value assessment model was used to evaluate the ecosystem service value of Yichun City, and the relationship with the social and economic development was analyzed. The results showed that the total ecological service value provided by the Yichun municipal system in 2015 was 2.62 x 10. 70 thousand yuan, the forest provides the highest value of ecosystem services, accounting for 91.60% of the total value, followed by water and grassland. The spatial distribution of ecological service value of 5.23% and 2.00%. is not obvious. Although Yichun is the high value area of the value of ecosystem services in Heilongjiang Province, the total value of ecosystem service value is total, The distribution of mean and per capita share is very uneven in each administrative area, and it is not in harmony with the social and economic development. According to the resources and environmental conditions of each district, it is still the important task to determine the scientific industrial structure and promote the coordinated development of the local ecological environment and economic construction.
