| Abstract: | According to the northwest natural, climate and resources, we built an eco-campus mode Of "pig or toilet-biogas-vegetable", then analyze its economic benefit. Take Xidazhai middle school as an example of eco-campus to introduce mode’s construction, and through financial analysis method to analyze the mode of "pig, toilet-biogas-vegetable". Results show that the net Present Value >0, the Economic Internal Rate of return (0.117) > Basic Discounted Rate, the benefit (1.102)>1and the mode has good econ... |
