鲁西北平原旱涝盐碱综合治理区划

旱涝盐碱是鲁西北平原的三大自然灾害,是该地区农业生产低而不稳的重要原因。这三种自然灾害有着密切的内在联系,应当综合认识,综合治理^2],同时,各地自然条件和旱涝盐碱情况不尽相同,必须因地制宜、各有侧重地分区分片治理^3,4]。鲁西北平原旱涝盐碱综合治理区划就是根据这个原则制定的。

COMPREHENSIVE REGIONALIZATION FOR THE HARNESS AND CONTROL OF DROUGHT, FLOODING, SALINIZATION AND ALKALIZATION OF NORTHWESTERN PLAIN IN SHANDONG PROVINCE

The northwestern plain of Shandong is a main part of the plain of the Huang-Huai-Hai rivers and it is also an important area of grain and cotton production. However, because of the influence of drought, flooding, soil salinization and alkalization, crop yield in the area is still low and unstable. These calamities with closely internal interrelations should be considered integratedly in order to harness and control them in a reasonable way. The main measures for harness and control the calamities should be conducive to (a) the improvement of the water and salt regimes in the area on the basis of drainage, (b) reasonable exploitation and regulation of water resource on the basis of well irrigation, (c) reasonable land use integrated with maintenance and promotion of soil fertility and enhancement of rcsistance to the disasters, and (e) popularization of forestation and improvement of the ecological environment.
