摘要:
[目的]揭示陕西省耕地利用生态效率、生态环境质量的时空分布特征,阐明生态环境质量对于耕地利用生态效率的响应方式,进而为陕西省农业高质量发展提供科学支撑。[方法]以陕西省为研究区域,基于遥感数据,计算了遥感生态指数以表征陕西省生态环境质量; 利用SBM模型测度陕西省耕地利用生态效率; 采用地理加权回归模型探究了生态环境对耕地利用生态效率的响应。[结果](1)2005年、2010年、2015年和2019年陕西省耕地利用生态效率总体上处于中等水平,有88%以上的地区属于低效率、较低效率和中等效率等级;(2)2005年、2010年、2015年和2019年陕西省生态环境质量在不断提高,黄土丘陵沟壑区和毛乌素沙地等地区生态环境质量有明显改善,空间格局总体上保持“南高北低”不变;(3)陕西省耕地利用生态效率和生态环境存在显著的正相关,相关关系空间分布具有不均衡性。[结论]陕西省生态环境与耕地利用生态效率的协同发展模式并不稳定,还需进一步探索与巩固。
Abstract:
[Objective] The aim of this study is to explore the response mode and degree of ecological environment to the ecological efficiency of cultivated land use, which is of great significance for realizing the coordinated development of agricultural sustainable development and ecological environment protection. [Methods] Shaanxi Province was taken as the research area. Remote sensing ecological index was calculated to characterize the ecological environment quality of Shaanxi Province based on remote sensing data. SBM model was used to measure the ecological efficiency of cultivated land use in Shaanxi Province. The geographical weighted regression model was used to explore the response of ecological environment to the ecological efficiency of cultivated land use. [Results](1)In 2005, 2010, 2015 and 2019, the ecological efficiency of cultivated land use in Shaanxi Province was generally at the medium level, and more than 88% of the areas were classified as low efficiency, low efficiency and medium efficiency.(2)In 2005, 2010, 2015 and 2019, the ecological environment quality of Shaanxi Province was continuously improved, and the ecological environment quality of loess hilly and gully region and Mu Us Sandy Land were significantly improved, and the spatial pattern remained high level in the south and low level in the north in general.(3)There was a significant positive correlation between the ecological efficiency of cultivated land use and the ecological environment in Shaanxi Province, and the spatial distribution of the correlation relationship was unbalanced. [Conclusion] The synergistic development model of ecological environment and ecological efficiency of cultivated land use in Shaanxi Province is not stable, and needs to be further explored and consolidated.
