Abstract: |
This paper retrospects to the basic situation of implementing returning arable lands to forestry engineering in the vast areas of China, expounds the importance of evaluating the ecological efficiency of returning arable lands to forestry engineering. On the basis of summarizing the research on evaluation method, the paper puts forward a target system to evaluate ecological efficiency of returning arable lands to forestry engineering from 4 aspects as water conserving efficiency, water and soil preservation efficiency, atmosphere quality improving efficiency and microclimate improving efficiency, The paper also provides detailed target measuring method. |
Key words: returning arable lands to forestry engineering ecological efficiency evaluating method |
