南水北调西线工程调水区地质灾害问题

南水北调西线工程地处青藏高原东南部,规划三期工程从长江上游的通天河及其支流雅砻江、大渡河年总调水170×108m3,经输水隧洞穿越江河分水岭巴颜喀拉山入黄河上游,解决黄河上、中游地区严重的水资源短缺问题。本文在对调水区气象气候、水文、地貌、岩性构造等环境背景条件分析研究的基础上,初步论述了西线工程建设中将面临的主要地质灾害问题,如水库诱发地震、库岸再造和岸坡变形、多年冻土和季节冻土、泥石流和严重水土流失、深埋长隧洞的高地温、高地应力岩爆、涌水及碎屑流等。针对这些灾害问题和西线工程目前现状,提出了五点指导性防灾建议。     

Assessment and exploitation of the waterfront resources in the middle and lower reaches of the Yangtze River

Waterfront resources are important and special kind of natural resources in the marginal area between land and water. The Yangtze River, the longest river in China, is not only rich in waterfront resources, but also has favorable development conditions with great potentiality. Aided by large-scale underwater topographic map, the major factors of the waterfront resources in the middle and lower reaches of the Yangtze River, such as the stability, the water depth and the natural conditions for port construction, are assessed in this paper respectively on the basis of the overall investigations. The results show that: (1) the waterfront resources are abundant in the middle and lower reaches of the Yangtze River, but lack of perfectly combined high grade waterfront; (2) there exists an obvious regional difference in the natural quality of the waterfront along the Yangtze; (3) the fore-bank water depth and waterfront stability are the main natural factors related to the waterfront quality in the middle and lower reaches of the Yangtze River; (4) the waterfronts along the Yangtze are mainly used for port, warehouse and industrial purposes; and (5) the waterfronts near important cities are highly used, especially the high-quality waterfronts. In addition, some suggestions for the development and utilization of the waterfront resources are presented in this paper.

利用山西省资源优势发展环保型有机无机复肥

山西省有三分之二的中低产田土壤急需改良,研制和扩大环保型有机无机复肥是山西农业可持续发展的需要。利用山西的几种可改良土壤的矿物原料和有机废料与无机化肥配合试制出的“长效肥力宝”是一种新的环保型有机无机矿物复混肥。经初步试验,结果表明其肥效优于常规化肥的增产效果,土壤的有机质和N、P、K等养分含量有明显的提高。发展该类产品既保护了环境,又促进了农业生产的发展。
