摘要

建立了基于环境条件的热带生态系统响应SITE模型,用于估算能量通量。通过生态系统模拟和野外测量,对巴西马托格罗索州Sinop市辖区50 km的半落叶森林的净生态系统CO2交换(NEE)进行了分析。利用涡动相关方差技术,在42米高的塔中连续测量了冠层CO2储存量和CO2通量。在生态系统建模中,采用SITE方法估算新能源经济性。SITE需要进行参数化设置。在雨季,SITE模型对NEE的估计效果较好。

Modelling Net Ecosystem CO2 Exchange by Simple Tropical Ecosystem Model
SITE model was developed to study the response of tropical ecosystems according to environmental conditions for estimating of energy fluxes. This study analyzed the net ecosystem of CO2 exchange (NEE) by ecosystem modeling and field measurements in a semi deciduous forest located at 50 km of Sinop municipal district, Mato Grosso, Brazil. Continuous measurements of canopy CO2 storage and fluxes of CO2 were made in a tower of 42 m height using an eddy covariance technique. For ecosystem modeling was used SITE to estimate the NEE. SITE required a setting of parametrization. The better performance of the SITE model to estimate NEE was obtained during the wet season.
