Abstract
Masses of cultivated land resources, which are the pith of land, are submersed by water conservancy and hydroelectric engineering, so it is very important to evaluate the cultivated land resources scientifically. It not only benefits the calculation of investment budgetary estimate of water conservancy and hydroelectric engineering, but also protects legal property rights and interests of reservoir migrators in the aspect of compensation for cultivated land resources acquisition. The value of cultivated land resources, submersed by water conservancy and hydroelectric engineering, should consist of natural character value, social security value, food security value and ecological and environmental value, which are evaluated according to the principle of comprehensive, dynamic and maneuverable. And then study on calculation method and mathematical model of four different values are put forward, based on which an instance is evaluated and the result is that the value of cultivated land resources submersed by the illustrational water conservancy engineering is 127761.6 yuan/mu.
