某500kV输变电工程项目，线路全长2×879km。该工程所在地区主要为平原地区，占用的土地主要为农田，线路跨越两条河流和一条铁路，线路沿线无国家级野生动物，在评价范围内没有县级以上的自然保护区。工程投资5亿元，该工程的变电所周围和线路一定范围内存在着居民住宅和学校。 根据以上内容，回答以下问题。 该项目线路周边的居民较少，宜采用什么措施避免产生不利影响。
In recent years, we have all watched the increasing commercialization of the campus. The numerous advertising, posters and the golden arches of fast food outlets may be an affront (侮辱) to our aesthetic sensibilities, but they are, arguably, no worse than ugly. Some of the other new features of commercialized campus life do, however, constitute a serious threat to things we rightly respect. "Privatization" and the "business model" are the potential menace. What do these notions mean To me, they involve an increased dependence on industry and charitable actions for operating the university; an increased amount of our resources being directed to applied or so-called practical subjects, both in teaching and in research; a proprietary treatment of research results, with the commercial interest in secrecy overriding the public’’s interest in free, shared knowledge; and an attempt to run the university more like a business that treats industry and students as clients and ourselves as service providers with something to sell. We pay increasing attention to the immediate needs and demands of our "customers" and, as the old saying goes, "the customer is always right". Privatization is particularly frightening from the point of view of public well-being. A researcher employed by a university-affiliated hospital in Canada, working under contract with a medicine-making company, made public her findings that a particular drug was harmful. This violated the terms of her contract, and so she was fired. Her dismissal caused a scandal, and she was subsequently restored to her previous position. The university and hospital in question are now working out something similar to tenure (终身任职)for hospital-based researchers and guidelines for contracts, so that more public exposure of privately funded research will become possible. This is a rare victory and a small step in the right direction, but the general trend is the other way. Thanks to profit-driven private funding, researchers are not only forced to keep valuable information secret, they are often contractually obliged to keep discovered dangers to public health under wraps, too. Of course, we must not be too naive about this. Governments can unwisely insist on secrecy, too, as did the British Ministry of Agriculture. Fisheries, and Food in the work they funded in connection with the bovine (迟钝的)spongiform encephalopathy epidemic(牛脑海绵体流行病). This prevented others from reviewing the relevant data and pointing out that problems were more serious than government was letting on. It is implied in the passage that______.
