Description

Cultivated land layout planning system and method based on data map Technical Field The invention relates to the technical field of farmland planning, in particular to a farmland layout planning system and method based on a data map. Background The existing application method of machine learning in farmland layout planning generally relies on feature mining and model prediction of multi-source data to realize the intellectualization and the precision of planning. The method comprises the steps of firstly collecting multidimensional data such as soil properties, topography, climate conditions, resource matching and the like of cultivated lands, simultaneously integrating information such as historical planting structures, yield data, optimization cases and the like to construct a dataset comprising natural characteristics and production characteristics of the cultivated lands, then extracting characteristics of soil fertility, irrigation accessibility and crop adaptation degree through data preprocessing (such as missing value filling and characteristic standardization), and then carrying out association analysis on the characteristics by utilizing a machine learning model (such as random forest, neural network, support vector machine and the like), such as identifying adaptation planting types of different cultivated lands by using a classification model, predicting indexes of yield and resource consumption under different layouts by using a regression model, or dividing cultivated land blocks with similar optimization requirements by using a clustering model. The conventional farmland layout planning method lacks integration of farmland multisource information. For example, the partial planning is divided only according to the area or soil fertility of the cultivated land, dynamic soil moisture content of remote sensing monitoring and supporting capability data of intelligent irrigation are ignored, so that classification of cultivated land blocks is rough, an area which really needs to be optimized cannot be identified, a cooperative system of a core block and the supporting blocks is not constructed, and spatial association and resource sharing relations among different cultivated lands are ignored, so that the optimized cultivated land is difficult to form linkage benefit, and diversified cultivated land conditions and development requirements in the area are difficult to adapt. The partial areas have cultivated lands needing to be lifted and matched cultivated lands needing to depend on core area resources, but a single planning scheme cannot meet the differentiated requirements of different areas, and the matched areas are easily ignored due to excessive focusing on the core area, so that planned landability and suitability are limited.
