生态盈余

宜春2004年生态盈余1.32ha/cap，生物多样性指数0.88，发展能力指数1.26，万元GDP生态足迹2.61ha；

In 2004 , for Yichun , ecological surplus is 13.2 ha / cap , ecological diversity index is 0.88 and development capacity index is 1.26 , ecological footprint of 10 ~ 4 yuan GDP is 2.61 ha ;

以目前的趋势来看，生态盈余状态最多能维持5～15a。

According to current trend , ecological surplus could only maintain 5 ~ 15 years .

研究表明，我国1961-1977年为生态盈余期，1978-2003年为生态赤字期。

The research indicates , our country in 1961-1977 year was ecology earnings time , but in 1978-2003 years was ecology deficit time .

生态盈余与生态赤字的拐点出现在1975年，且赤字呈负增长趋势，生态赤字的出现表明凉州区农业生态系统处于不可持续的状态。

The transformation period between ecological remainder and deficit was in 1975 , and the deficits had negative increment with acceleration in recent years .

氮肥的高量投入导致农田生态系统氮素持续盈余。

High amount of nitrogen fertilizer result in continous nitrogen surplus in agro-ecosystem .

除2006年长海县处于生态亏损，其他年份都能处于生态盈余。

Except in 2006 , Changhai county has ecological surplus in other years .

通过生态足迹计算可以看出，影响城步县生态盈余消失的主要原因是：①生态生产性土地需求类型过于集中。

Seen from the result , the main reasons that caused the ES disappearance were : ( 1 ) the demand type of the ecological productive area was too concentration .

结果表明，岳西县2002年人均生态足迹为0.694942hm2，人均生态承载力为0.771222hm2，人均生态盈余为0.076280hm2，岳西县处于可持续发展状态。

Yuexi was in the condition of ecological surplus in 2002 , and the ecological surplus was 0 . 076 280 hm2 per cap .

结合生态占用的相关分布图指出生态需求、生态承载力、生态盈余/赤字以及GDP生态需求的空间分布有从东南沿海地区向西北内陆地区渐变的趋势。

The distribution of ecological demand and ecological capability and ecological deficit / remainder and the ecological demand of GDP shows the gradual change from southeast to northwest .

结果表明，该区人均生态足迹逐年下降，人均生态承载力波动较小，而人均生态盈余逐年增长。

The results showed that throughout the study period , the EF per capita decreased , ecological carrying capacity ( ECC ) per capita almost had no change , and ecological surplus per capita increased .

基于对呼和浩特的实地考察和历年的统计年鉴数据，通过生态足迹的计算模型和生态承载力的计算模型得出呼和浩特生态赤字大于生态盈余，表现出不可持续发展状态。

Based on the visit and the Statistical data yearly , through ecological footprint model and the calculation of the ecological carrying capacity model , ecological deficit reaches more than ecological surplus is speculated in Hohhot , which shows the state is not sustainable .

因此，随着总能值生态足迹的增长，能值生态赤字也逐年增加，由原来1980年的生态盈余1599.05万hm~2增加到2005年的生态赤字11385.40万hm~2。

Therefore , as the total energy ecological footprint grew , the energy ecological deficit increased yearly , from ecological surplus 15.9905 million ha in 1980 to in 2005 to an ecological deficit of 113.854 million ha in 2005 .

从生态赤字的组成部分来看，耕地、牧草地和水域均处于生态赤字状态，且有逐年扩大的趋势，而建筑用地和林地处于生态盈余状态。

Among the components of the ecological deficit , farmland , pasture and water are all in a state of ecological deficit , with a trend of increasing , while construction sites and woodland in a state of ecology surplus .

基于生态足迹理论，从经济系统对自然资源的需求和供给角度出发，对江苏省阜宁县县域生态经济系统进行研究，提出了万元GDP生态赤字（盈余）的概念。

Based on the theory of ecological footprint , the ecological economic system in Funing County of Jiangsu Province was analyzed in view of the demand and supply of natural resources by economic system .
