工业化和城市化进程决定了中国将处于资源环境压力的上升阶段。矿产资源、特别是能源供给不足，煤炭消费在我国能源结构中仍占70％以上，由于煤炭的大量使用，造成大气严重污染；能源结构的落后，已成为我国经济发展的主要障碍。为保护环境、减少污染、提高居民生活质量，现在必须对能源结构加以改善和优化。近年来石油、LPG进口不断增加，因此，天然气产品作为清洁能源将会日益得到人类的青睐，天然气产业将会受到政府的高度重视而积极推动发展。

铜川市新区位于陕西省中部，处于关中平原向陕北黄土高原的过渡地带,是关中经济带的重要组成部分，介于东经108°34′-109°29′、北纬34°50′-35“34′之间，是陕西省省辖市，新区现有人口20万左右，至2015年达到30万，总面积为45平方公里，城区为18平方公里左右，作为新建市区，政府大力推行天然气洁净能源，从而减少污染，加快城市经济建设。

The industrialization and the urbanized advancement had decided China

will be in the resources environment pressure the ascent stage. The mineral

resource, is specially the energy supplies is insufficient, The coal expended in our

country energy structure still accounted for above 70%, As a result of the coal

massive uses, cause the atmosphere to pollute seriously; Energy structure's

backwardness, has become our country economic development the chief obstacle.

In order to protect the environment, the reduced pollution, to improve the resident

quality of life, must improve and the optimization to the energy structure. In recent

years the petroleum, LPG the import increased unceasingly, Therefore, the natural

gas product will take the clean energy to obtain humanity's favor day by day, the

gas industry will receive the government to take seriously to promote the

development positively.

Tongchuan newly developed area located at Shanxi Province middle, Is

in the guanzhong plain to the North Shanxi Loess Highlands zone of transition, is

the Guanzhong economical belt's important component, Is situated between the

east longitude 108°34 ' - 109°29 ', the north latitude 34°50 ' - 35 “34 ', Is the

Shaanxi Province municipality, The newly developed area existing population

about 200,000, achieves 300,000 people to 2015, The total area is 45 square

kilometers, the city is about 18 square kilometers, As newly built urban district,

The government carries out the natural gas pure energy vigorously, thus the

reduced pollution, speeds up the urban economy construction.

Key words: Fuel Natural gas；Fuel gas pipe network；Environmental protection;
