- 摘要:
- 对昆明市生态红线区非生态用地的转变提出了3种方案，利用2005年土地利用变更调查数据，计算和分析了非生态用地转变前后红线区的生态效益价值。结果表明：（1）2005年生态红线区的现状总生态效益和单位面积效益价值分别是35.48亿元和2.16万元/hm2；（2）非生态用地按低、中、高方案实施转变后，红线区的生态效益比现状分别增加了9.8%、12.4%、15%；（3）按低方案，红线区生态效益的提高，主要取决于区内耕地面积比例较大的区县，增值最高和最低的分别是宜良县和盘龙区；（4）按高方案，红线区生态效益的提高，则是由区内建设用地和耕地面积比例之和较高的区县所决定，增值最高和最低的分别是五华区和禄劝县；（5）高、低方案的效益值，分别代表红线区将来生态效益的最大值和最小值，而中方案的效益值，则最能现实地反映红线区将来一般生态效益状况。
- Abstract:
- Three schemes,concerning changing the non-ecological use lands into ecological ones in Red-line areas in Kunming district,were put forward.Applying the land use investigation data in 2005,this paper calculated and analyzed the ecological benefits value of the Red-line areas before and after changing the non-ecological use lands into ecological ones.The results showed that:(1) The gross ecological benefits value of current situation and that of per hm2 were respectively 35.48×108 Yuan and 2.16×104 Yuan in the Red-line areas in 2005.(2)Compared with the current situation,the ecological benefits value of the Red-line areas would increase 9.8%,12.4% and 15% respectively if the low,medium and high scheme were implemented.(3) According to the low scheme,it would depend mainly on the districts and counties which farmland area has higher proportion in the Red-line areas to enhance the ecological benefits of the Red-line areas.Yiliang county and Panlong district are respectively the highest and lowest in raising value.(4) While according to the high scheme,it would rested on those districts and counties with higher proportion in area scale of the farmland and constructing use land in the Red-line areas to improve the ecological benefits of the Red-line areas.Wuhua district and Luquan county is the highest and lowest respectively in raising value.(5)The values computed with high and low scheme respectively represent the maximum and minimum of ecological benefits in the future in the Red-line areas,while the counterpart according to medium,could most realistically reflect the average condition of ecological benefits of the Red-line areas in the future.
