The Zhujiang (Pearl) River Delta is the rapid economic development region in China since the opening and reform door policy
was carried out in 1978. Being the rapid development of industry and city, the impact on the aquatic environmental quality
was significant. The pollution caused the water quality descended and the ecological system degraded, and also impeded the
economic development. The characteristics and problems of the aquatic environment are: the capacity of aquatic environment
is large but hasn’t been utilized rationally, the water quality is influenced by saline sea water and tide current, the main
pollutants are organic matter and the pollution is going heavier, the concentration of pollutants change seasonally. The countermeasures
of aquatic environmental protection are: carrying out the environmental functional regionalization and controlling the total
amount of pollutant discharge, revising the industrial structure and making a rational industrial arrangement, raising the
rate of waste water treatment and making a full assessment of the water conservancy project. 相似文献

After nearly 20 years of construction,we have successfully solved a series of hydrologic sedimentaryand environment problems encountered during the construction of the big deep water harbour inLianyungang which can now accommodate ships of 50000 tonnage.With the economic development,the channel of 50000 tonnage will be built soon, and of 100000 tonnage is under planning. Theconstruction of the international container shipping hub at the harbour is being accelerated in anticipationof the opening of the second Eurasian land bridge.The future development of the harbour will givegreat impetus to the local economy of Lianyungang City and make it an international city. 相似文献

中川花岗岩在空间上呈同心圆环状分布,由三个单元组成,三个单元之间,岩石矿物学、地球化学成分作有规律性地变化,这种变化与圈层结构变化相适应。构造岩浆演化具有同源性,连续性、脉动性;岩体上升侵位方式为具有多次脉动性的复式气球膨胀体;在空间上与金、铀关系密切,但为成金仅提供热源,而为成铀既提供物源,又提供热源。 相似文献

Regional and village land resource issues and environmental conditions in the Rapti zone, western Nepal are discussed in the context of the Himalaya Environmental Degradation theory (Ives 1987). Ecological stress is indicated in agriculture to forest land ratios, farmland capability, and land use change. Intra-regional differences and specific local conditions indicate the complex dimensions of environmental and development issues in the Rapti zone. 相似文献
