Thehigh values of the niche-fitness (the maximum is 0.958) indicate that the environmental conditionsbasically meet the requirements of crops in the area. Suitability evaluation of single crop showsthat the degrees of suitability are satisfactory. Comprehensive suitability evaluation shows thatthe acreage for grade 1 (highly suitable for cultivation) accounts for 18.16% of the totalcultivated land area, whereas the acreage for grade 3 (critically suitable) and grade 4 (unsuitable)only for 8.9%. The main factors limiting the potential land productivity are cation exchangecapacity (CEC), available phosphorus content and accessibility level of road.展开更多
