For many years, it is due to successively blasting operation, wantonly excavating ore and stone, discharging large amout of waste water and dregs from factories, mines and other enterprises, and destroying forest and grass cover without restraint, serious environment nuisance has been produced, such as seizing and destroying a number of land resources, worsening water quality commonly, violent soil and water loss, silting of many river beds, reservoirs and irrigation canal systems, serious environment pollution and so on. All these threaten the security of life and property of millions of inhabitants and harm the realization of four modernization.

山西省是我国著名的能源重化工基地。多年来,由于工矿企业强行爆破施工,乱开滥采矿石,排放大量废水弃渣,任意破坏林草植被,已造成严重的社会公害,如侵占和破坏大量土地资源,水质普遍恶化,水土流失剧烈,河床、水库和渠系逐年被淤塞,环境污染严重,等等。这些都直接威胁着千百万居民的生命财产的安全,危害“四化”建设。现在,有些工矿单位已开始处理废水弃渣,综合利用矸石和高炉水灰,并用工程措施和生物措施治理水土流失;已开始重视生态环境保护。

This paper describes the suitability of Astragalus adsurgens by aerial so- wing and technology of improving aerial sowing effects in the area where an nual precipitation is about 250 mm. It indicates that the major factors affecting effects of aerial sowing Astragalus adsurgens are drought, low temperature and calamitles caused by wind and sand. To dotermine suitable sowing time (late June or early and middle July before raining season begins), sown areas (a large area where the cultivated land is turned into waste or turned into forest and grass land) and plowing surface and treating seeds are the efficient technical measures to increase aerial sowing effects. The experimental results showed that the dense high grassland could be formed after Astragalus adsurgens grown for three years, survival seedling rate is 85.5-100%, fresh grass yield is 493.5 kg/mu (the highest is 2, 034.3 kg/mu), which is 6.8 times as much as that of closed waste land. Aerial sowing Astragalus adusurgens has shown markable economic and ecological benefits.

本文比较深入地探讨了在年降雨量250毫米左右条件下,沙打旺适于飞播的能力和提高飞播效果的技术。干旱、低温和风沙灾害是影响沙打旺飞播效果的主要因子;选择适宜的播期(雨季来临前夕的6月下旬至7月上、中旬)、播区(具有大面积退耕地和撂荒地)并采取地面处理和种子处理,是提高飞播效果有效的技术措施。试验结果表明,沙打旺播后第三年,即可形成郁闭的高草地,成苗面积率达85.5-100%,平均亩产鲜草493.5公斤(最高可达2,034.3公斤),为同期封禁荒地产草量的6.8倍。经济改益和生态效益显著。

This thesis deals, in general, with the physical geographical condition of Beijing area, and analyzes the main signs of ecologic environment deteriorating in Beijing mountains. They are the low of forest in mountains; the decrease in the quality of forest and grasses, as well as productitivity; serious soil erosion and soil layers becoming thiner;and the frequent calamity such as flood, haid,mud-rock flow, and drought. According to the relation between soil erosion and obliguity of the earth surface, precipitation and its intensity,the plant coverge and the degree of reclaiming wasteland, the key of the synthetic harness is the prevention of soil erosion, and the crux is resumption of the mountatins plants.Base areas of forest,fruit,and stock-raising should be built respectively, according to the natural conditions and resources in the mountains. Strengthen the development in energy resources and adjust the production structure of forestry, husbandry and agriculture.

论文简述了北京自然地理概况。分析了山区生态环境恶化的主要标志:一是山区森林覆盖率低;二是森林和牧草质量及生产力降低;三是水土流失严重,土层变薄;四是山洪、冰雹、泥石流、干旱等自然灾害频繁。依据水土流失规律与地面坡度、降水与降水强度、植被覆盖度及开垦程度等因素的相关关系,北京山区综合治理的关键是防止水土流失,而防止水土流失的钥匙是恢复山区植被。依据北京山区自然资源的优劣,分别建立林、果、牧业基地,加强能源开发,调整林、牧、农业生产结构。
