Why Baidu Hi is such development pouring foreword main is helpless, because the development base of Baidu is a webpage,the search just is searched after obtaining position of a leadership, web2.0 times comes, the success that the network develops is technical advantage not just, capture an user or the user is agglutinant, become a crucial factor especially the arrival of rich passenger times, baidu is timely rolled out Baidu space with a view to to grow end theory, a series of products of Baidu, such as Baidu knows, Baidu is stuck, Baidu space is sealed undoubtedly, just follow the evolution that at the development trend of whole internet network passivity accepts changes of course, baidu knows, Baidu is stuck it is the successful act that duplicates hard undoubtedly what special need is worth to say is, of Baidu space roll out, baidu space justs to be rolled out, show individual character as main factor stresses development, so that locate Baidu space directly later,be the community that make friend, had been apparently be Baidu Hi roll out prepared

百度Hi为什么是这样倒序发展的呢主要的是无奈，因为百度的发展基础是网页搜索只是搜索达到一个领导地位后，web2.0时代到来，网络发展的成功不仅仅是技术的优势，抓住用户或者是用户粘性，成为一个至关重要的因素非凡是博客时代的到来，百度适时推出了百度空间着眼于长尾理论，百度的一系列产品，诸如、百度贴吧、百度空间无疑都是未知的，只是跟随于整个互联网络的发展趋势而被动采取的发展变革当然，、百度贴吧无疑都是难以复制的成功举措非凡需要值得一说的是，百度空间的推出，百度空间甫一推出，就把个性展示作为一个重要因素突出发展，以至于后来直接把百度空间定位为交友社区，已经很明显是为百度Hi的推出做预备了

The land use pattern had changed by a relatively large margin in Neijiang city from 1997 to 2005. The main tendency of this change is that with remarkable reduction of cultivated land that decreased by 9936.11hm~2, unutilized land and water area, while garden land, forest land that increased by 7032.23 hm~2, grass land and building land increased notably. And during the research time, the speed of land use type change reduced from garden land, traffic land, forest land, residential areas and industrial and minings land, cultivated land, unutilized land to water area. The main trend of general dynamic degree changed from progressive increase to degression. From the analyses of land use diversion matrix, we know resulting in the quantity change of land use was that cultivated land being occupied by construction,adjustment in structure of agriculture and the implementation of the national reforesting formerly cultivated land policy in Neijiang city.

结果表明：1997～2005年间，土地利用类型发生较大幅度变化，总体上呈现耕地、未利用地、水域面积显著减小和园地、林地、牧草地、建设用地面积增大的趋势，其中耕地面积减幅最大，达9936.11hm~2，林地增幅最大，达7032.23 hm~2；土地利用类型变化速度依次为园地＞交通用地＞林地＞耕地＞居民点及工矿用地＞未利用地＞水域，其中园地为2.67％，水域为-0.01％，综合土地利用动态度呈现先递增后递减的趋势；从土地利用类型转移矩阵分析得出，建设用地占用耕地、农业结构内部调整、&退耕还林&是导致内江市土地利用类型数量变化的重要原因。
