秸秆禁烧与综合利用问题分析及对策建议 总被引:2,自引:0,他引:2
焚烧秸秆屡禁不止,既有主观因素也有客观原因.主观上,随着农村经济的发展和广大农民生活水平的提高,许多传统的秸秆利用方式相继被淘汰,人们往往采取一烧了之的办法.客观上,机械收割面积迅速扩大,留茬过高而影响播种.杜绝焚烧秸秆,从根本上解决秸秆焚烧问题,不仅是各级政府的一项重要职责,而且需要广大农民的主动参与和社会各界的积极关注. 相似文献

正环保部近日发布了10月6-12日全国一周秸秆焚烧火点卫星遥感监测情况。监测情况显示,目前各地已陆续进入秋季秸秆焚烧高峰期,在18个省份共监测到疑似秸秆焚烧火点517个,按照火点数量前5名省份依次为河南、辽宁、山东、河北、湖北。国庆期间,本刊记者来到了河北农村,发现焚烧玉米皮也成了当地农村的环保问题。 相似文献

编辑同志:你们好!每到"三秋"和"三夏"季节,农民为抢收、抢种,把剩余秸秆绝大部分在田间直接焚烧处理,这样不但造成资源浪费,而且带来严重的大气污染问题,极易引发火灾事故,特别是在公路两侧焚烧秸秆,严重影响了机动车行驶的安全,交通事故频发,由此所带来的经济损失难以估量。现在,"三秋大忙"已经开始,各地纷纷按照上级环保部门的要求,召开秸秆禁烧会议,因此,如何做好秸秆禁烧和综合利用,减少环境污染题,是我们当务之急。据初步分析,农民焚烧秸秆的主要原因,一是收割机在收割时为方便作业,节约成本,往往留茬较高,不利于下一季的耕作; 相似文献

每年的六月麦收时节来临,各地狼烟四起,一些地方农民为抢农时就地焚烧秸秆,致使麦田里烟雾缭绕,造成交通事故、火灾等险情不断,焚烧麦秸已成了让环保和交通部门头疼的事。为此,本刊记者殷玉婷采访了国家环保总局环境监察局环监二处助理调研员金冬霞同志。金冬霞介绍,焚烧秸秆不仅浪费资源、污染环境,影响人们正常生活和身体健康,影响飞机起降和交通干线及高压输电线路安全,进而影响国际及城市形象,也会烧毁农作物及树木造成经济损失。我国焚烧重点区有安徽、江苏、四川、陕西、河南、河北、山西、山东。2005年夏季通过卫星遥感监测到火点390… 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

The increase in the number of tourists visiting a coast is desired by most of the countries for economic reasons. However, this increase in tourism may cause pollution of the sea. This can be only avoided by proper planning and by predicting the carrying capacity of the coast in terms of sea pollution. This is especially important for developing countries where part of the wastewater is discharged without any treatment into the sea.In the present study the beaches were classified according to their use — and consequently the amount of waste discharged into the sea — into four groups: (1) coasts that are used only for swimming and recreational purposes; (2) coasts used simultaneously for dwelling, swimming, and recreational purposes; (3) coasts along which only dwellings exist; and (4) natural and man-made harbors, i.e., coasts used as shelters. During the survey,40,320 observations were made between December 1985 and February 1988 to determine the effect of the number of tourists on seawater quality. The results obtained were analyzed by a multilinear regression program to obtain an empirical equation giving the extent of the sea pollution in terms of coliform concentration as a function of population density and some other environmental factors.The equations derived in this study enable the determination of the carrying capacity of a beach in terms of pollution as well as the expected degree of pollution corresponding to a given population density. Furthermore, it allows the prediction of the extra carrying capacity that can be obtained by improving the waste-disposal conditions. 相似文献
