Computer Intelligent Evaluation Model and Characteristics of Spatiotemporal Pattern of Ecosystem Service Information Digitization in Shaanxi Province

Abstract

Shaanxi Province is located in the hinterland of China, in the important position of connecting China East, central region and northwest and southwest. This study is based on Shaanxi Province as the research area, combined with 2000, 2010 and 2018 land use / cover, quantitative assessment of ecological supply services, regulation services, support services, support services, and cultural services and its cold hot spot time and space. The results showed that: (1) 2000–2018, Shaanxi land use patterns changed, mainly as the forest area continued to increase, the area of cultivated land is slightly reduced, and the area of construction is increased faster; (2) 2000, 2010 and 2018 The total value of Shaanxi ecosystem services is 890.76 billion yuan, 913.88 billion yuan and 911.198 billion yuan, which are rising in fluctuations; (3) 2018, Yulin City is in the total value of the total value of ecosystem services; Hanzhong City and Ankang City is in Unit area value hotspot area. This study passed the scientific reference for future ecological planning through the analysis of the value of the ecosystem service in Shaanxi Province and its cold hot spot.
