中国帮助降低世界人口增长速度

The world population hits 7 billion people on Oct. 31st. As the most populous nation in the world, China implemented rigorous family planning policy 30 years ago. Many policy makers in China believe it has avoided 400 million extra births.
世界人口10月31日达到70亿，作为世界上人口最多的国家，中国30年前实行了严格的计划生育政策。中国的很多决策者认为，这减少了4亿的超生人口。

Most Chinese experts agree the population of China would have hit 1.7 billion had it not been for the family planning policy.
大多数中国专家认为，如果没有实行计划生育，中国的人口将达到17亿。

In the late 1970s, China introduced the family planning policy. Previously, people were encouraged to have large families. But out of concern for natural and energy resources - and lately out of environmental concerns - families were encouraged to have one child.
上世纪70年代末，中国引进了计划生育政策。以前是鼓励人们建立大家庭。但是，出于对自然资源和能源的担忧——以及近来出于对环境的担忧——国家鼓励家庭只生一个孩子。

The effects of the policy are debated, but for a leading Chinese demographer, the policy had postponed the arrival of the world population of 7 billion by at least five years.
这个政策的影响是受争议的，但是对于中国一名主要的人口统计学家来说，该政策使世界人口达到70亿推迟了5年才到来。

Lu Jiehua, professor from Peking University, said, "The reform and opening-up policy has not just helped China’s economy. It has also promoted population control. Over the past 30 years, we have
contributed to a favourable environment for the country’s economic development and social stability."
北大教授Lu Jiehua表示：“改革开放政策不仅帮助中国发展经济。它还推动了人口控制。过去30年里，我们为国家经济发展和社会稳定创造了一个有利的环境。”

But China still faces serious challenges. There is a serious gender imbalance due to the traditional preference for boys. Also, due in part to the family planning policy, China suffers from an ageing population.
然而，中国仍然面临严峻的挑战。由于重男轻女的传统思想，性别比例严重失衡。计划生育政策也是中国人口老龄化的部分原因。

Dean Zhai Zhenwu from Population Institute of Renmin University, said, "We must follow the family planning policy for it has decreased the world population and promoted economic development. But with the development of population, China is facing disparities between an ageing population and population distribution."
人民大学人口学院院长翟振武指出：“我们必须坚持计划生育政策，因为它使世界人口减少，促进了经济的发展。但是随着人口的发展，中国正面临着人口老龄化与人口分布之间的差异。”

Re-evaluating and improving the existing family planning policy will be one of the major tasks in the future to promote a more balanced population development.
重新评估、改进现行的计划生育政策将成为未来促进人口更加平衡发展的主要任务之一。
