At the end of 1970s, remote sensing technology was introduced into China and has been used since then in the activities of forest resource inventory, especially in estimating forest stock volume.
以中国林科院为主的一批林业科学工作者 ,积极将其应用于森林资源调查工作 ,特别是森林蓄积量的估测。
With remote sensing technology being widely used in the investigation of forest resources,especially in the remote sensing estimation of the forest stock volume,remote sensing method can save time,work and budget in comparison with the traditional method.
随着遥感技术广泛应用于森林资源调查工作,特别是森林蓄积量的遥感估测,将比传统方法省时、省力,节约经费。
A lot of foresters use this new technology in the activities of forest resource inventory, especially on estimating forest stock volume.
2 0世纪 70年代末 ,遥感技术被应用于中国的森林资源调查工作 ,特别是森林蓄积量的估测 。

the difference of water distribution is rather big in time and space,average water resource quantity of each person and acre is small.
但是时空分布差异大、水土资源分配不均,人均地均水资源占有量少;
If reckoned per capita, however, ours is lower by far.

the per capita possession of grain came to 424.4 kilograms, or 1.5 times the 1978 figure;
人均占有粮食424.4公斤,是1978年的l.5倍;
In recent years, China's per-capita grain output has been kept at around 400 kg, and the country's grain reserves have been maintained at the highest level in history.
近年来中国人均粮食占有量稳定在400公斤左右,粮食储备量保持在历史最高水平。
and by 2030 the population will peak at 1.6 billion and the total demand for grain will be approximately 640 million tons, based on 400 kg per person.
2030年人口达到16亿峰值,按人均占有400公斤计算,总需求量达到6.4亿吨左右。
The per capita forest area is 0.128 hectares in the whole country, about one fifth of the per capita forest area in the world.
全国人均占有森林面积为0.128公顷,相当于世界人均森林面积的1/5;
However, the per capita grassland is only 0.33 hectares, only one half of the per capita area in the whole.
但人均占有草地仅0.33公顷,为世界人均面积的一半。
However,because of the unequal possession of cultivated lands,the large amount of the agricultural surplus was owned by the feudal landlords.
但由于耕地占有不均,大量的农业剩余为封建地主所有。
The green coverage rate reaches 35.3%, which allows the per capita green area up to 7.9 square meters.
城市绿化覆盖率达35.3%,人均占有绿地面积7.9平方米。
