浅谈农村生态环境恶化原因及治理措施

近些年来,我国社会经济迅猛发展,人民的生活水平日益提高。农村也发生了很大变化,农民过上了相对富裕的生活。但随着工农业生产的发展,一些乡镇企业的兴起、乱用农药等,使农村生态环境恶化日趋严重,并制约了农村的生态平衡和可持续发展。     

松嫩平原盐碱化草原治理模式的建立及其应用

由于自然及人为因素,造成松嫩平原草原盐碱化现象严重、生态环境日趋恶化、草原生物多样性减少、生产力降低、草原防风固沙、调控水土等生态功能下降,直接影响草业及当地人民生活水平和生活质量的提高,盐碱化已成为生态环境建设和农业发展的重要障碍之一.因此,草原生态环境恶化是迫在眉捷,亟待解决的问题.采用以振动深松为主,施生化土壤改良剂和农艺措施为辅的集成技术改良盐碱化草原,可科学调节土壤水、肥、气、热条件,增大土壤蓄水容量,改善土壤的理化指标,使土壤由重度盐碱化土变为轻度盐碱化土,草原生态环境得到大大改善.同时针对不同盐碱化程度进行科学地分类治理,实现了投入少、见效快、产出最大化,具有广阔地推广应用前景.

Water impoundment modes of flood utilization for the Songnen Plain

Taking the Songnen Plain as the research region and basing on the structural division of river water resources, the impounding models of flood water utilization are proposed. Considering the water requirement, potential impoundage and the degree of risk, two modes of the flood water utilization are developed: full impounding and partial impounding. A risk assessment method is put forward according to variation of the flood storage capacity before and after impounding water. A representative hydrological year is taken as an example to analyze the application of the model at the down-stream of the Nenjiang River. It is found that the model is very useful for the flood utilization and protection. For flood utilization, the spring drought can be relieved and the risk of impounding water is also acceptable. For flood protection, the river flood peak can be largely reduced and the impounding water can increase the river discharge at the low water period, at the same time the structure of river water resources can be improved as well.

Application of nitrogen-fixing cyanobacteria in restoration of saline and alkaline soils of Songnen Plain in China

The salt-resistant nitrogen-fixing cyanobacteria 888 was experimentally applied to the reclamation of saline and alkali soil in Songnen Plain in China. The pH, electrical conductivity (EC) and sodium adsorption ratio (SAR) of different saline soils were studied and compared. Results show that different saline soils exhibit various physico-chemical properties. Saline-sodic soils in Songnen Plain are ameliorated by using nitrogen-fixing blue-green algae 888 in the experiment. It is indicated that cyanobacteria 888 can grow in saline and alkaline soils, and the conditions favorable for its growth are soil moisture of 50% and dry algae inoculation at 0.03 mg/cm2. The main actions of nitrogen-fixing cyanobacteria are keeping the adsorbability of rubber sheath for sodium, increasing the organic matter content of the soils and decreasing the pH and the degree of salinity in the soils. But the arid climate and soil depth are the main factors that limit the restoration of saline and alkaline soils.
