基于土地利用变化的红壤丘陵区生态系统服务价值分析
|
摘要
文章选取生态系统服务价值变差贡献率作为指标,研究2008—2017年间兴国县各土地利用变化对此指标的影响,结合灰色综合关联度,研究了其他4项指标对生态系统服务价值的贡献程度。研究结果显示,生态系统服务价值的降低主要是由林地面积减小引起的,由于市场需求增长和政府政策鼓励等原因,园地面积不断增长,成为仅次于林地面积的影响因素。不同研究时期内,总人口数、城镇化水平、第一产业占比与社会固定资产投资4项经济指标与生态服务价值的关联度有所差异,其中,前3项指标与生态系统服务价值高度关联,但是随着时间的推移,各指标对生态系统服务价值的影响差异逐渐减小,仅第一产业占比与生态服务价值呈正相关,其他3个指标均呈负相关。
This paper selects the contribution rate of ecosystem service value variation as an indicator to study the impact of land use change on this indicator in Xingguo County from 2008 to 2017, and studies the contribution of other four indicators to ecosystem service value by combining with the grey comprehensive correlation degree. The results show that the decrease of ecosystem service value is mainly caused by the decrease of forest land area. Due to the increase of market demand and government policy encouragement, the garden area has been growing continuously, which is second only to the forest land area.In different research periods, the total population, urbanization level, the proportion of the primary industry and the four economic indicators of social fixed asset investment have different degrees of correlation with the value of ecological services, of which the first three indicators are highly correlated with the value of ecological services. However, with the passage of time, the differences in the impact of each indicator on the value of ecological services gradually decrease, with only the proportion of the primary industry positively correlated with the value of ecological services, while the other three indicators are negatively correlated.
