Space-time analysis of the changing patterns of population pressure on the ecological environment in China

This paper examines the temporal change and spatial variation of population pressure on the ecological environment in China. We have collected sufficient data from the statistical yearbooks of 31 provincial administrative areas in 1990, 1995, 2000, 2005, and 2010. Using a geographic information system (GIS) and relevant models, we analyzed the trend of the population pressure on ecological environment and the change of the gravity center of ecological environment quality. We conclude that: (1) generally, population pressure on the ecological environment in China was becoming higher during 1990–2010, especially in some areas where the population and environment were in serious imbalance and the ecological environment experienced severe pollution; (2) during a certain period, population pressure on the ecological environment was becoming lower in some areas, but the ecological environment was getting worse; (3) the areas with super-high population pressure on the ecological environment were Beijing, Tianjin, and Shanghai; (4) the gravity center of population pressure on the ecological environment and the center of ecological environment quality move differently during the study time period, but the general trend was similar – both of them were moving from west to east. Based on the analysis, this paper also provides some policy suggestions on the control of ecological environment quality.

广西柳城县农业生态环境的定量评价

建立了包括生态资源、人类驱动和系统响应3方面17个指标在内的农业生态环境定量评价指标体系,结合广西柳城县的实际情况,运用模糊综合评价模型,对当地农业生态环境进行定量评价。结果表明,柳城县农业生态环境质量属于一般水平,当地自然生态条件较好,虽受人类活动影响较大,但生态系统运行依然正常。该评价结果与当地实际情况相符,表明该评价指标体系具有较强的科学性和实用性。依据评价结果,提出了改善柳城县农业生态环境的对策和建议。     

建立我国生态环境标准体系的初步构想

我国的生态环境标准极其薄弱，建立生态环境标准体系是我国生态环境保护的迫切需要。借鉴我国目前针对污染防治的环境标准体系，提出了我国生态环境标准体系的基本框架，以及生态环境标准制订的原则和重点。     

济南市泉城公园生态环境需水量初步研究

以生态优先原则、兼容性原则、最大值原则和水质为重点的原则,采用生态环境需水量计算法中的直接计算法、功能法及换水周期法,从林地生态需水量、草地生态需水量、人工河湖蒸发需水量、人工河湖净化需水量、生物栖息地需水量、人工河湖渗漏需水量、景观与娱乐需水量和公园内设施用水等八个方面,对济南市泉城公园的生态环境需水量进行了初步研究。结果表明,在2005年气候条件下,济南泉城公园的生态环境需水量大约为1．0467×10^6m^3。在此基础上对提高泉城公园水资源利用价值及节约用水等方面提出了建议。

植被恢复对矸石山生态环境效应影响研究

以兴隆庄煤矿绿化矸石山和裸露矸石山为研究对象,研究了植被恢复对矸石山生态环境效应的影响.结果表明,植被的恢复重建了矸石山生态系统,改善了矸石山生态环境:气温平均降低3.7℃、空气相对湿度提高了7.1%,矸石山近地层SO2、NOx和TSP粉尘日均浓度分别降低了0.1471 mg/m3,0.0004 mg/m3 0.0389 Mg/m3矸石山植被的恢复增加了矸石山土壤比重,降低了土壤容重、提高了土壤有机质含量.
