Application of Remote Sensing Detection and GIS in Analysis of Vegetation Pattem Dynamics in the Yellow River Delta

Regional vegetation pattem dynamics has a great im- pact on ecosystem and climate change.Remote sensing data and geographical information system (GIS) analysis were widely used in the detection of vegetation pattern dynamics.In this study,the Yellow River Delta was selected as the study area.By using 1986, 1993,1996,1999 and 2005 remote sensing data as basic informa- tion resource,with the support of GIS,a wetland vegetation spa- tial information dataset was built up.Through selecting the land- scape met...     

Application of Remote Sensing Detection and GIS in Analysis of Vegetation Pattern Dynamics in the Yellow River Delta

Regional vegetation pattern dynamics has a great impact on ecosystem and climate change. Remote sensing data and geographical information system （GIS） analysis were widely used in the detection of vegetation pattern dynamics. In this study, the Yellow River Delta was selected as the study area. By using 1986, 1993, 1996, 1999 and 2005 remote sensing data as basic information resource, with the support of GIS, a wetland vegetation spatial information dataset was built up. Through selecting the landscape metrics such as class area （CA）, class percent of landscape （PL）, number of patch （NP）, largest patch index （LPI） and mean patch size （MPS） etc., the dynamics of vcgetation pattern was analyzed. The result showed that the change of vegetation pattern is significant from 1986 to 2005. From 1986-1999, the area of the vegetation, the percent of vegetation, LPI and MPS decreased, the NP increased, the vegetation pattern tends to be fragmental. The decrease in vegetation area may well be explained by the fact of the nature environment evolution （Climate change and decrease in Yellow River runoff） and the increase in the population in the Yellow River Delta. However, from 1999 2005, the area of the vegetation, the percent of vegetation, LPI and MPS increased, while the NP decreased. This trend of restoration may be due to the implementation of water resources regulation for the Yellow River Delta since 1999.     

有机高分子絮凝剂AUF的研制及其除油效果测定

以尿素、甲醛为原料合成脲醛树脂，加入环氧氯丙烷对树脂进行改性，再加入三乙铵进行季胺化，得到改性脲醛树脂季铵盐絮凝剂AUF。在WEMCO浮选机上考察AUF的除油性能及最佳合成条件。结果表明：AUF投药量为10mg／L时，出水中油浓度达到国家排放标准；当甲醛、尿素、环氧氯丙烷三者的摩尔比为2：1：0.5，季铵化温度为80～110C，反应时间为4～5h时，得到的絮凝剂AUF除油效果最好。

DTC型采出水净化剂研究进展概述

二硫代胺基甲酸盐（DTC）是一种高效、多功能采出水净化剂，它由二硫化碳与伯胺或仲胺反应生成二硫代胺基甲酸，然后再与碱反应而制备。其作用机理是与采出水中的铁或其它溶解金属反应形成絮体，絮体迅速聚结形成网状而包裹油，从而使油去除。DTC具有净化作用快，除油功效高，适用于分离、重力沉降和浮选等水处理过程。目前，国外DTC型冷水剂已发展到第三代。
