梅县地区的水土流失是严重的,年侵蚀深度一般约1.3—3毫米,年侵蚀模数每平方公里分别为1,956吨和4,500吨,个别地方更大。这在坡陡土薄的石质山区是惊人的,比北方的水土流失危害更严重,更深远。水土流失的治理,不单纯是科学技术问题,而且涉及社会科学,因而治理工作必须加强领导,全面规划,因地制宜地采取生物措施和工程措施相结合,加强预防、治理和管理,长期不懈地坚持下去。
Soil erosion in Meixian County is serious with annual erosion depth of about 1.3-3 mm and annual erosion modulus of 1,956 tons and 4,500 tons per square kilometer, respectively, in some places. This is astonishing in steep and stony rocky slopes, more serious and far-reaching than the soil erosion in the north. The management of soil and water loss is not only a matter of science and technology, but also involves the social sciences. Therefore, we must strengthen leadership and overall planning of governance and adopt biological measures and engineering measures in accordance with local conditions so as to enhance prevention, management and management and persevere in a long period of time .
