LIU Hua, JU Hong-bo, FU Mao-yi, YANG Xiao-sheng
2008, 21(Z1): 6-13.
Abstract:
Landsat TM images of 1984 and 1999 that cover the whole Fuyang Citywere used to analyze the dynamicchange p rocess of bamboo and other land-use types. The results of analyze indicated: that from 1984 to 1999, therate of land-use change was rap id. For the rate of change of each land-use type, garden p lot was the most rap idone, and farmland was the slowest one. The area of bamboo forest decreased. The annual average rate of decreasingof was 2. 47%. Most of decreased bamboo forest was transferred to other forest. There was regional diversity ofbamboo forest change in the 25 towns of Fuyang. From 1984 to 1999, the stability of other forest was the highest,and it is the type that got the most transference from other land-use type. So the area of other forest increased largelyin the changed period.

2008, 21(Z1): 14-19.
Abstract:
This paper takes Culaishan Forest Farm, Shandong Province, and Tieshanp ing Forest Farm, Chongqing,as test sites. The airborne discrete return LiDAR data were collected in May of 2005 and Sep tember of 2006seperately. The forest heightwas estimated for both test sites. Through the camparison of the two sites, the effects ofairborne L iDAR point density on forest height estimation were analyzed. The results demonstrated that itwas feasibleto use low and high point density airborne L iDAR data to estimate forest height. Quartiles could give good treeheight estimation in the low L iDAR point density case. The accuracies from high density L iDAR data showeds onlya little better than low density data. The high density data could be used to estimate finer scale forest height evenindividual tree height, which is helpful to minimize necessity of the number filed p lots.

Erdos salina wetland borders on Kubuqi Desert and Maowusu Desert. It is a wetland of internationalimportance to p rotect Larus relictus and its habitat. Hydrophily biology has sensitivity on circumstance change. Thestudy is on Tao-A Haizi and Hongjian Nur in 2006. The survey measured according to Investigation Handbook ofFisheries Natural Resources in Inland Waters. Hydrophily biology diversity index was calculated by Shannon Wiener. After checking, it was found that there were 14 kinds of phytop lankton in Hongjian Nur and 4 kindsphytop lankton in Tao-A Haizi. There were 8 kinds of zoop lankton in Hongjian Nur and 9 kinds in Tao-A Haizi.There were 9 kinds of zoobenthos in Hongjian Nur and none in Tao-A Haizi. Hongjian Nur ismiddling pollution andTao-A Haizi is severely polluted according to diversity index.

2008, 21(Z1): 80-84.
Abstract:
Obtaining land-cover information by classification method from remote sensing images was a basic andimportant project. The CBERS images of Zhuzhou City in 1999, 2003 and 2007 were classified with supervisedclassification methods based on the establishment of land-cover classification system, the land-cover information wasextracted and its dynamic changes were analyzed. The results indicated that: it was effective to use CCD data ofCBERS to monitor land-cover dynamic information by remote sensing in hilly areas in the middle of China. From1999 to 2007, the p roportion of forest land and water body and construction land were gradually increased inZhuzhou City, resulting in the decrease of farm land and other land. The increases of forest land and constructionland was sharp but the increasing rate became slightly. In conclusion, the results could p rovide some scientificevidence for the government of Zhuzhou City to make decision in land resources use and thesustainable development.

2008, 21(Z1): 95-99.
Abstract:
The paper introduced the concep ts and connotation of sustainable forest management , discussed thedialectic relationship of sustainable forestmanagement and integrated monitoring of forest resource, and summarizedthe current status and development trends of forest resource monitoring in the world. The paper also indicated thatthe goals of integrated monitoring of forest resource were enriched by sustainable forest management, and integratedmonitoring of forest resource was an important guarantee and app roaches of indicators collection for sustainable forestmanagement. In recent years, the objectives of forest resource monitoring have changed from timber resource tointegrated monitoring of forest resource and environment in developed countries. Besides forest growth indicators,the important indicators of forest health status and ecological environment were also added to monitoring contents.Many advanced instruments were used to continuous and automatic monitoring. It could reduce the workload andcosts of field monitoring and imp rove the accuracy and continuity of data.

2008, 21(Z1): 112-117.
Abstract:
With the development of horticulture companies in Zhejiang Province , they began do business withforeign companies. The import & export values of flower & p lants have increased constantly, but the import valuewas less than the export value all the while. The most important imports were seeding and bulbs, and the largestparts of the export were made by cutting foliage. Several large and medium-scale companies do such business.Several factors, such as constraints in resources and breeders rights, marketing, overelaborated phytosanitarycertificate p rocedures, and vicious competition, seriously limited the enterp rises to play the most of their superiority inp rices, to raise the grade of exported p roducts, and to extend export. So it is needed for the cooperation ofgovernment, the custom, the p lant quarantine bureaus and enterp rises to solve the problems concerned.

HONG Zhi-meng, YE Gong-fu, KANG Wei-feng, PAN Hui, GUAN Qing-wei
2008, 21(Z1): 138-141.
Abstract:
As a sub-ecosystem of city ecosystem, urban vegetation is the principal natural factor of the city and it canadjust the environment of the city. The investigation of traditional urban greening mainly by combining artificialinvestigation with statistic method, needs a great amount of people and money, and data accuracy and timelinesscan’t satisfy city development. But by combining high resolution remote sensing data with GIS method, we canextract urban greening data and precisely countits spatial distribution. The paper combines remote sensing data andtakes Xiamen city as an examp le to extract urban vegetation feature data and make a relative analysis. The studyshowed that urban vegetation has lower diversity index, which only reaches 1. 14 in Xiamen. The whole vegetationlandscape doesnpt has app rop riate distribution pattern with 0. 65 of dominance and 0. 41 of evenness, there is aphenomena that less vegetation landscape controls the whole greening pattern. Based on the study, the advice wasbrought forward for vegetation plan in Xiamen.
