| 摘要: |
| 就近年来中国宜能非粮地研究方法的合理性进行分析,并确定各适宜性指标的适宜范围。首先总结利用土壤调查统计资料和应用遥感数据及地理信息系统(Geographic Information System,GIS)获取宜能非粮土地资源的方法,汇总这2个方法所用的调查统计资料和数据库,评价研究方法及其所用数据库的合理性。然后,讨论前人研究结果,提出更完善的宜能非粮地的适宜性指标评价体系,包括地面坡度、有效土层厚度、土壤质地、土壤碱化度、土壤含盐量、无霜期、≥10 ℃年积温、水分条件、排水条件、集中连片条件、生态条件和污染超标条件等,最后分析确定各指标适宜范围。 |

| Abstract: |
| Using proper methodology to determine the suitable land resource is crucial to the development of non-food energy plants production.This paper reviewed the methodology and suitability evaluation index of non-food land suitable for energy plant production in China.A method to get the resource of non-food land suitable for energy plant production was summarized by combining both soil survey statistic data and remote sensing data obtained from Geographic Information System (GIS).All data were collected and the research method and the database were further evaluated.After discussed the previous research, a more perfect suitability evaluation system of non-food land suitable for energy plant production was put forward after discussed the previous research.The system included surface slope, effective soil depth, soil texture, soil alkalization degrees, soil salinity, frost-free season, ≥10 ℃ year accumulated temperature, water condition, drainage condition, land concentrated condition, ecological condition and exceeding pollution index.And the value range of each index was identified. |
