Legal analysis: combined with the comprehensive factors such as the planning of surrounding towns, industrial layout and land development. Based on the main industrial layout of Yancheng section of Linhai Expressway, this paper studies the planning scheme of Yancheng section of Linhai Expressway, including (but not limited to) site survey, scheme design (including but not limited to line direction, overall scheme, interchange node scheme, engineering investment calculation, construction time sequence analysis, etc. ), optimize the design effect, and the whole process control and other services. Simultaneously carry out research on land spatial control planning and prepare a research report on land spatial control planning scheme. The research scope of this project is along the line. The following work is carried out respectively: First, according to the planning and construction scheme of land space control in the feasibility study, the planning scheme, technical standards and main interchange settings that have an important impact on the occupation of land space resources are put forward, and passages are reserved. The contents include: technical standards, planning scheme, scale and layout of controlled projects such as interchanges, extra-long bridges and extra-long tunnels, and preliminary statistical results of land use scale and land use types; If a project with high geological risk is predicted, geological investigation should be carried out according to the feasible depth. Secondly, according to the depth and accuracy requirements of the spatial control of "three belts and three lines", the spatial relationship of "three belts and three lines" is explored respectively; Whether it can cross the relevant planning, and whether the scale and type of land occupied by the project meet the relevant requirements, a clear conclusion should be given; If it is really necessary to cross the buffer zone of nature reserve or the secondary protection zone of water source protection, it shall fully demonstrate the necessity of crossing and put forward measures to ensure that the environmental quality will not be reduced; If permanent basic farmland must be occupied, the necessity, rationality and supplementary scheme of occupation shall be demonstrated; According to the survey results, optimize the line location and reduce the interference to related planning.

Legal basis: Bid 2.2 division and land space control planning research project of the planning scheme of Yancheng section of Linhai Expressway * * This bidding project is divided into 1 bid, namely LH bid, and the work contents are as follows: (1) Combining the comprehensive factors of the surrounding towns planning, industrial layout and land development of Yancheng section of Linhai Expressway, the planning scheme of Yancheng section of Linhai Expressway is studied around the layout of major industries. Including (but not limited to) site survey, scheme design (including but not limited to line positioning, overall scheme, interconnection node scheme, project investment calculation, construction time sequence analysis, etc. ), design effect optimization, whole process control and other whole process services. (2) Simultaneously carry out research on land spatial control planning, and prepare a research report on land spatial control planning scheme. The research scope of this project is along the line. The following work is carried out respectively: First, according to the planning and construction scheme of land space control in the feasibility study, the planning scheme, technical standards and main interchange settings that have an important impact on the occupation of land space resources are put forward, and passages are reserved. The contents include: technical standards, planning scheme (based on the horizontal and vertical alignment of 1: 10000 topographic map), the scale and layout of controlled projects such as interchanges, extra-long bridges and extra-long tunnels, and the preliminary statistical results of land use scale and land use types; If a project with high geological risk is predicted, geological investigation should be carried out according to the feasible depth. Secondly, according to the depth and accuracy requirements of the spatial control of "three belts and three lines", the spatial relationship of "three belts and three lines" is explored respectively; Whether it can cross the relevant planning, and whether the scale and type of land occupied by the project meet the relevant requirements, a clear conclusion should be given; If it is really necessary to cross the buffer zone of nature reserve or the secondary protection zone of water source protection, it shall fully demonstrate the necessity of crossing and put forward measures to ensure that the environmental quality will not be reduced; If permanent basic farmland must be occupied, the necessity, rationality and supplementary scheme of occupation shall be demonstrated; According to the survey results, optimize the line location and reduce the interference to related planning.
