In order to resolve the problems of water shortage in China, one should consider the integration of irrigation projects, water conservation and economical utilisation of water. Irrigation projects mean exploiting water resources. To transport water from rivers beyond their own flowing reaches, it is necessary to prove its applicability before undertaking construction work. Sinking wells can be done only in areas with a plentiful amount of groundwater. Reservoirs also should be constructed only in areas with sufficient water resources and where less arable land has to be irrigated. Water conservation is connected closely with afforestation or protection of forests as well as protection from industrial pollution. Economic utilisation of water resources includes using water wisely to grow crops, and economising on its use in industry and for domestic purposes.

The agricultural resources of China vary with its different geographic regions. China is divided into six geographic regions and the climate, flora and fauna of each are described, together with the ecological relationship between them. Suggestions are given of how best to exploit, utilise and protect these resources.

Forests should be thought of not merely as “timber”, but also as treasuries of plants and animals as well as “green reservoirs”. The preservation and management of montane forests are therefore of importance. Different ways should be adopted according to the corresponding conditions of four montane forest regions of China. Afforestation in the humid eastern plains and southern rolling hills should be paid great attention, because these areas have much more rainfall, deep and fertile soil and sufficient atmospheric heat. Protection forests planted on farmlands and along the southeastern seaboard not only raise the output of crops, but also provide timber, fuel and forage. It is necessary to strengthen the rewarding utilisation system of forest resources. The current irrational remuneration of afforestation workers and forest engineering workers doing similar jobs but for different wages must be changed.
