Abstract

A method for determining a candidate area for rice planting, the method comprising: extracting a floodplain area from a water body distribution map according to time-series water body index data; Calculate the slope conditions of the floodplain according to the elevation of the floodplain and carry out multiplicative weighted calculation on the inundation index of the pixel and the distance from the stable water body according to the slope conditions of the floodplain, to obtain the rice planting candidate area and candidate classification in the floodplain. The method provided by the invention extracts the flooded area in the water body distribution map according to the time-series water body index data, makes full use of the remote sensing big data, and can extract the inundation characteristics of the flooded area more accurately. , the convenience of irrigation, can more scientifically determine the rice planting candidate areas in the floodplain.

Description

technical field [0001] The invention relates to the field of geographic information and remote sensing, in particular to a method for determining a candidate area for rice planting. Background technique [0002] Different growth stages of rice have water requirements, especially in the greening stage, the paddy field should maintain a certain water layer to create a relatively stable temperature and humidity environment for the seedlings, promote the early development of new roots, and accelerate the greening. Because of rice's dependence on water, rice irrigation is a decisive factor in determining rice yield. As an important freshwater resource, large lakes are an excellent supply for irrigated rice cultivation in addition to natural rainfall. Therefore, it is very important to select the planting candidate area technology suitable for rice growth and convenient irrigation in the lake floodplain and surrounding areas. [0003] The traditional determination of planting ca...
