1. the optimized remote sensing evaluation method in a crop rotation cycle, evaluation object are to make crops production obtain the period of crop-rotation of ecological and economic benefit;

  • At first select crop rotation condition, ecology and economic benefit to be best crop rotation zone as optimum crop rotation zone;

    Then decipher is carried out in the crops variation spatially in optimum crop rotation zone in the remote sensing image;

    And with the data of decipher result as the estimation crop rotation cycle;

    The actual period of crop-rotation that formula that foundation is relevant again and substitution interpret data are estimated crops is as the optimum period of crop-rotation;

    Finally the period of crop-rotation of these again that other crop rotation is regional crops compared with the optimum period of crop-rotation, and realization is to the optimum evaluation in this crop rotation cycle;

    The actual period of crop-rotation that formula that foundation is relevant again and substitution interpret data are estimated crops is meant that as the optimum period of crop-rotation following is that the described mathematical formulae of example, derivation, result of calculation and application process are applicable to the period of crop-rotation of all crops and the estimation of spatial variations with C crops and R crop rotationAfter the interpret data of M the small towns N continuous year remote sensing satellite image that has obtained C crops and R crop rotation zone, calculate C crops and R crop rotation cycle with following formula,
