沿海地区对外开放15年来,外资、合资、集体、个体企业在工业结构中的比重明显增加。它们均要求有良好的投资环境,依靠社会办企业。新兴工业多集中在城镇附近,厂址不少选在较关键的须加强环境保护的地区,如自然保护区,水源保护区等附近。在此情况下,必须按社会主义市场经济规律征收资源费和排污费等;须加强环境规划,建立环境管理系统,有效控制污染源;为保证受损环境得到恢复,必须加强环境建设和环境投资。 相似文献

This paper discusses briefly the elementary characteristics of the east China economic developing zone, and analyses the condition of urban atmospheric pollution, water pollution and ecological damage in this zone at present. It was brought forward that we must pay great attention to the environmental factors, and make the environmental impact assessment and environmental planning in the process of economic development in this zone. 相似文献

Wetland is one of the richest biodiversity areas in the earth. The main purpose of establishing wetland protected area is to protect biodiversity, and the protection of ecosystem diversity and landscape diversity is the key to protect biodiversity. In order to protect regional ecosystem and landscape, it is a good way to establish wetland comprehensive protected area which connected wetland nature reserves by habitat corridors. The Sanjiang Plain as a study area, its landscape evaluation index system on wetland protected area was studied, and some problems on landscape planning and ecology construction were further approached in this paper. It showed that establishing wetland comprehensive protected area is very important to protect regional wetlands, to maintain ecological balance,and to improve the sustainable development of agriculture and industry in this region. 相似文献

We investigated competition for food among two groups of six clone amagos (salmonids), Oncorhynchusmasoumacrostomus, in a laboratory experiment with different rates of food input. We examined the effect of temporal clumping of food resources
on the inequality of food sharing between competitors. Monopolization of food by dominants was greater at a low input rate
(one food item per 10 s) than at a high input rate (1 food item per 1 s). Aggressive behavior by dominants was more frequent
at the low input rate than at the high input rate; its purpose was presumably to interfere with the feeding behavior of subordinates.
We assessed the relative importance of three foraging factors (the number of approaches to food items, the chance per approach
and the gain per chance) in enhancing inequality in food gain between individuals. Dominants had a disproportionately high
chance per approach and gain per chance at the low input rate, but not at the high input rate. The chance of obtaining a food
item per approach depended on how many competitors approached simultaneously. The gain per chance depended on the competitive
ability of the approaching fish. There was an interaction between these components, such that the number of approaches affected
the chance per approach and gain per chance. We evaluated the independent effect of the chance per approach, and showed that
it was higher for dominants than for subordinates at the low input rate, but not at the high input rate. This implies that
subordinates changed their behavior and became more likely to avoid approaching food at the same time as dominants at the
low input rate.
