Traditional platform field model

(1) The Huang-Huai-Hai Plain is low in wetlands, with soil erosion in southern hilly areas and dense water networks in the Pearl River Delta.

(2) adjust measures to local conditions (water control)

(3) Fish pond-terrace model, Qianyanzhou three-dimensional agricultural model and Tangji agricultural model.

(4) Make China's traditional agriculture gradually develop into modern intensive management, and form a commodity agriculture with a certain scale and a commodity base of superior agricultural products. Maximize the transformation of resource advantages into economic advantages and improve resource utilization. Correctly coordinate the relationship between man and land, establish a benign ecological cycle, prevent the ecological environment from deteriorating further and improve the living environment.

This topic comprehensively investigates three successful measures in the process of land consolidation in China. According to the principle of adjusting measures to local conditions, three different three-dimensional agricultural models are established. Figure A is the fish pond-terrace model in the Huang-Huai-Hai Plain, Figure B is the three-dimensional agricultural model in the hilly and mountainous areas of the south, and Figure C is the pond agricultural model in the Pearl River Delta. These three modes of agricultural production not only improve the efficiency of agricultural production, but also follow the laws of nature, establish a virtuous circle and improve the living environment.
