The hillyland area in Donghai

Xinyi and Ganyu county is characterized by the plentiful sunlight and suitable heat resources. The good agroecological condition is generally coexisted with the bad one in this area. Because of the thin layer of soil

the poor supply of soil avaiable nutrient

the serious soil erosion

the seasonal drought

and the shortage of water resource

attention must be paid to develop aproject emphasizing the conservation of water resource. Analysis of the agricultural resources suggests that the efforts should be made to retain surface runoff

to enhance the capability of dispatching and preserving water

and to improve efficiency of water usage. To afforest trees and to build terraced fields are also essential for controlling soil erosion. The technique of deep ploughing and manure accumulation should be empolyed to set up a high effective agroecological system.To gradually realize a large-scale exploitation and an indust rial process

the agriculturalst ructure should be adjusted. The resources advantage should be identified to develop a diversified economy. This is a way to develop the economy and to approach the ultimate aim of agricultural integrative exploitation in this hilly countryside.
