| Abstract: | The alkili saline land in the western Songnen Plain is one of the important alkili saline areas in China. In recent decades, the total area of alkili saline land reaches 3,200,000hm 2 and increases by 20,000hm 2 per year on an average due to the natural and human factors. Besides, the degree of salinization increases, ecological environment teriorates and the good development of the regional economy are impeded. The measures to harness the salinized land should follow such principles as ecological continuance, economic continuance and social continuance. The comprehensive measures are as follows. First, the ecological engineering measures are to perfect the shelter forest, to strengthen the administration of grassland, as well as to raise reeds and fish in lakes and pools. Second, the agronomic measures are to strengthen the administration of cultivation, to introduce salinie enduring plants and to bring soil from other places where are not salinized to fertilize the poor soil. Third, the irrigation works should be set up so that the salt of soil are removed. Forth, small chemical plants are set up in order to make full use of the salt and alkili of the salinized soil. Therefore, the salinized land can be improved, the regional environment can develop in a good direction and the regional economy can develop in a good way. |
