On the coincidence between the Square Diagram of the Fu Xi s 64 hexagrams and the sectional drawing of the soil in alluvial plain by the Yellow River;

Based on the analysis of wind-sand disaster control and shelter belt status of the wind-sand impacted region in Yellow River floodplain in Shandong province,it was considered that the shelter system is single and defending capacity is weak,and the wind-sand movement of surface is still strong.

Algonquin,Astragalus adsurgens,Melilotus suaveolens in wind-sandy land of Yellow River floodplain were studied by field testing and indoor analysis.

Study on relationship of soil nutrients and various particlesin fluvo-aquic soils on the Yellow River flood plain,north China;

Research on the Relationship between Particles and Levels of Phosphorus in the Alluvial Soils on the Yellow River Flood Plain in North China;

A Study on Modes of Agro-forestry Management in Yellow River Flood Plain(Huangfan Plain);

Study on Field Water Dynamic of Coarse Sandy Soil in Huangfan Plain;

The Study of the Stability of Agriculture in Huangfan Plain in Qianlong Period of Qing Dynasty;

Through the determination of water characteristic curve, specific water volume, moisture constant,permeation coefficient, the situation of pore space and other physical characteristics of sandy soil in Huangfan plain, it was found that the empirical equation θ=AS -B could well simulate the water characteristic curve of soil during the low and medium suction (0.
