[Objective] The virtual cropland value of ubran areas of Gansu Province was accounted; and the spatial characteristics of invisible compensation loss rate was presented in order to definite two issues concered with the comppensation criterion of land expropriation and the situation of invisable compensation carried out at present around ubran areas of Gansu Province. [Methods] Income estimation approach

alternative method and ArcGIS10-based natural breakpoint method were utilized to compute and visualize the virtual cropland value and invisible compensation loss rate in Gansu Province in 2012. [Results] (1) Districts estimated with low and middle unit virtual value(per hectare) croplands covered the most parts of Gansu Province. The coverage were 35.71% and 42.86%

respectively; (2) Invisible compensation loss rate was mainly conducted at districts with high virtual value. The districts taked up 50.00% of the invisable compensation area; (3) Most districts with low

middle and high virtual values overlapped with the low

middle and high loss rates of invisible compensation. The overlapped areas were 66.67%

33.33% and 42.86%

respectively. The high overlap showed that the distribution of them was positive correlated; (4) Districts of productivity

resource and ecology accounted with low and high unit virtual value(per hectare) covered largely in Gansu Province. The low valued districts coverged 42.86%

35.71% and 42.86%; the high valued districts were 35.71%

28.57% and 42.86%

respectively. [Conclusion] The total virtual ecology values conducted at presnet was small so that it need to be replenished and subsequently the invisible compensation loss rate was relativly high; districts of the unit virtual values of productivity

resource and cropland had the low value at east and high value at the west aorund the province.
