摘要:

以上海市青浦区盈浦街道为例, 基于历史航空影像数据对区域生态资产进行调查, 通过生态资产损益表和相关分析等方法研究了2000—2021年盈浦街道生态资产变化趋势及原因. 结果表明: 2021年盈浦街道生态资产存量以耕地、湿地和草地为主, 质量等级总体为中级; 流量总价值为9.39 × 106元, 以水源涵养和废物处理价值为主. 2000—2021年期间, 盈浦街道生态资产总量呈显著下降趋势, 存量和流量分别下降了33.07%和22.97%. 城镇建设导致耕地生态资产迅速缩减是盈浦街道生态资产存量下降的主要因素, 退耕还林和退耕还草是盈浦街道林地和草地生态资产大幅增加的关键原因. 盈浦街道生态资产流量价值与夜间灯光强度、人口数量、国内生产总值、地表温度和高程呈负相关关系 (p < 0.001), 与坡度呈正相关关系 (p < 0.001).

Abstract:

This study investigated the ecological assets of Yingpu Street, Shanghai, using historical aerial imagery data. Using various methods, such as the ecological assets balance sheet and correlation analysis, changes in the ecological assets of Yingpu from 2000 to 2021, as well as the underlying mechanisms behind these changes, were analyzed. The results showed that, in 2021, the ecological assets of Yingpu Street mainly consisted of arable land, wetlands, and grasslands with an overall moderate quality. The total ESV(ecological service value) was 9.39 × 106 CNY (Chinese Yuan) and was mainly due to contributions from water conservation and waste treatment services. The ecological assets of Yingpu decreased significantly during the period from 2000 to 2021, with the stock and flow decreasing by 33.07 and 22.97%, respectively. Urban construction led to a reduction in farmland ecological assets and was the major contributor to the overall decline observed. Returning farmlands to forests and grasslands played a key role in the substantial increase of forest and grassland ecological assets. The ESV of Yingpu was negatively correlated with night light intensity, population, GDP (gross domestic product), land surface temperature, and DEM (digital elevation model) (p < 0.001), but was positively correlated with slope (p < 0.001).
