Due to the differences in natural environment, cultivated land quality and multiple cropping index, there Were differences in cultivated land output. The acreage standard determination of cultivated land quality became one of the key links for regional compensation mechanism of cultivated land preservation.

由于各区域的自然环境、耕地质量以及复种指数的不同，不同区域耕地产出存在差异，耕地质量面积标准的确定成为耕地保护区域补偿机制运行的关键环节之一。

差分坐标以其相关之拉普拉斯运算子在三维数位几何模型上已有许多的研究及应用，顶点的差分坐标计算是由顶点与拓扑上之相邻点的相对位置关系所求得，因此顶点之差分坐标代表了区域曲面起伏变化情况，差分坐标其方向会近似於区域法线方向而其长度会近似予区域平均曲率，此两项资讯为点云资料重要几何资讯。

First, the proposed scheme uses contourlet transform to extract multidirectional and multiscale texture information, and then obtains the feature points invariant to the affine transformation from the low and middle directional subbands by Harris-Affine detector. Second, the feature regions are adaptively computed by the feature scale of the local structure and normalized by U transform. The watermarking is embedded adaptively in those characteristic regions which are normalized. Finally, by vector quantization, several copies of the watermark are embedded into the no overlapped local feature regions in different directional subbands.

首先，用Contourlet变换提取出多尺度、多方向的纹理信息；再用Harris-Affine检测算子从变换域的中、低频方向子带中提取出仿射不变特征点，结合自适应局部结构的特征尺度确定特征区域，并用U变换对其归一化处理，水印就自适应地嵌入到归一化后的区域中；水印嵌入采纳矢量量化的策略，将水印信息重复嵌入到不同方向子带、多个不相交的局部仿射不变特征区域。

The change of the rural governance in the part of the State's viewpoint, the change of economic and political institution in rural area , the adjustment of law relation among familial members , and the evolvement of the social structure all have impacts on the effectiveness of family support for the elderly and oldster's welfare.

本文以治理和善治为分析框架，在实证研究的基础上，通过对传统时期、集体化时期、后集体时期的乡村治理与老人福利变迁的历史考察和后集体时期不同区域类型的乡村治理与老人福利的差异比较，得出如下结论：(1)不同时期老人福利状况不同，并不是家庭养老模式发生了变化，而是家庭养老的制度基础发生了变化，其关键因素是支持农村社区组织控制社区经济和约束社区成员的国家意识形态、经济体制、政治制度、法律文化等方面发生了变化；(2)中国发展是不均衡的，后集体时期，我国治理农村的制度框架基本相同，都是乡政村治、分户经营，但不同的地区的老人福利也有很大的差异，其主要原因是不同区域类型的村庄有不同的社会结构，其老人的社会地位和不孝行为所受村庄公共舆论约束力不同；不同区域的乡村组织状况不同，其乡村干部保障老人福利的意愿和力度不同；(3)在现有的乡村治理模式中，选举老人特别是在村庄定居的退休干部担任村组干部，发展自治性的老年协会和开展经常性的、群体性的老年文体娱乐活动，可以提高老人福利、改善乡村治理。

This project will study the benefit assessment on the ecology engineering of the greenway of highway interchange, at the design、construction and as-built stages. In this case, the ecology engineering of the greenway of highway interchange, including eco-pond and eco-island to substitute the green space, ecological corridor to reduce the habitat fracture, overfall to increase the Oxygen Saturation of the eco-pond, and the relative way to compatible the original environment. Furthermore, the case study on the problems during and after the construction provide some example for the same case in the future to reduce the impact to the original ecology environment.

本论文藉由交流道绿带区域采用之生态工程来探讨交流道绿带区域从规划、施工阶段到完成后所造就工程效益，如交流道绿带区域规划以生态池与生态岛取代绿地营造湿地环境、生物廊道降低栖地破碎化、跌水区增加生态池水中含氧量及相关近自然设计手法促使与周遭生态景观结合予以评估工程造就之效益，并藉由施工过程与完工后浮现之问题作为日后类似工程规划之范例，有助於减少对於既有生态环境之冲击。
