The study aimed at theoretically demonstrating the relationship between regional ecological qulity and Eucalyptus spp. plantation planting driven by economic benefit. Based on remote sensing technology (RS), global positioning system (GPS) and geographic information system (GIS), as well as document research, field investigation, RS interprete, RS inversion (NDVI, FVC, biomass, NPP) and spatial analysis, we took Guangxi Yuanxiao Reservoir watershed as an object and did some research on dynamic spatio-temporal ecosystem service of Eucalyptus spp. plantation conmminy and Pinusmassoniana community. The ecosystem service included water conservation, environment purification, carbon fixed and oxygen emission, product provision, soil conservation and biodiversity protection. The results are as follows. (1) NDVI and FVC were applicable to remote sensing inversion of various vegetation parameters. (2) Average unit ecosystem service value of Pinusmassoniana community was much better than that of Eucalyptus spp. plantation community. (3) Ecosystem services of Eucalyptus spp. plantation increased with the growth of year and the ecosystem values of mature trees were close to Pinusmassoniana, which meant that the plantation itself would not lead to problems such as water and nutrient excessive consumption; Pinusmassoniana deforestation and Eucalyptus spp. plantation rotation influenced ecological quality of the reservoir watershed greatly. In conclusion, violent human disturbance driven by economic benefit was the main reason for the significant decline in ecological quality of Eucalyptus spp. plantation area.
