为研究我国实行的天然林保护工程对工程区内农户经济收入的影响，通过在湖北省、四川省和重庆市三地以农户为对象的问卷调查，分析天然林保护工程对工程区内农户经济收入、能源消费的影响，并提出相关政策建议：政府应对天然林保护工程区内的农户给予经济补偿；应该采取措施来减少农户薪柴使用量和农户能源支出；应采取措施加大天然林保护区内的投资和经营，确实增加农户的经济收入。

In recent years, many countries are strengthening their own legislation of EEZ fishery resources'maintenance and management, such as Norway's Law of the Marine Fishery (June 3.1983) and Law of EEZ (Dec 17.1976); USA's Law of Fishery Protection and Management (issued in 1976, revised for the last time in 1996), Management Law of Littoral Zone (1972), Regulations of Marine Mammal Protection (1972) and so on.

近年来，各国不断加强本国EEZ渔业资源养护和管理立法，如挪威的《海洋渔业法》(1983年6月3日)和《专属经济区法》(1976年12月17日)；美国的《渔业保护和管理法》(1976年颁布，1996年最后一次修订)；《海岸带管理法》(1972年)、《珍贵稀有生物品种保护条例》(1972年)、《海洋哺乳动物保护条例》(1972年)、《海洋保护、研究和禁猎区条例》(1973年)、《濒临绝种生物条例》(1973年)、《美国水产养殖条例》(1980年)和《美国渔业促进法》(1980年)等。

The assessment result shows: the infirm zone of the aquifer basically distributes in the limestone area of low Ordovician -top Cambrian, which the cranny is uncovered and overgrown, the area is also the direct recharge area of spring basin. In addition , in the rivers valley area of Jin xiuchuan and Bei sha river, because the leakage of the river is serious, the contamination can leak easily to the groundwater in the area of surface and near the river, so this area also is the infirm zone. Frail zone distributes in the uncovered area of mid-Cambrian which the canny upgrowth is commonly, parts of the zone distributes the relatively impervious layer such as shale. In the north-west area where is the down-rivers of two rivers, the alluvium is thick, the protection to the limestone is good.
