## 5 Analysis and Results
### Value Compatibility Analysis  
The VCA calculation was carried out. According to [PERSON]'s VCA [23], the landscape value compatibility index (_LVCI_) is introduced [5] to reveal the overall compatibility of brownfield redevelopment value with given planning, pollution distribution, management projects and related policies, and to judge community attitudes and their spatial distribution characteristics. The formula for calculating the degree of compatibility [23] is as follows (the grid is used for calculation):  
\[LVCI=\frac{R}{R_{max}}\times 10 \tag{1}\]  
\[R=\sum_{i=0}^{n}C_{i}V_{i} \tag{2}\]  
where _LVCI_ represents the compatibility value of a grid; \(R\) represents (\(i=0\)) the aggregate value of a grid value density; \(R_{max}\) represents the highest density aggregate value in all grids; \(n\) represents the number of landscape value types owned in the grid; \(C_{i}\) indicates the compatibility coefficient of a Class I landscape value with planning and management

During the interview and investigation, the interviewees were asked to describe the impact of the current brownfield redevelopment plan on its marked values to understand their views on redevelopment. Based on the analysis of the interview content, the compatibility coefficient between the six landscape values of community residents and the redevelopment plan is determined through comprehensive judgment. Interviewees were asked to assign a compatibility score for each value relationship on a scale that ranged from \(-5\) (the brownfield landscape value from interviewees and current planning are highly incompatible) to \(+5\) (the brownfield landscape value from interviewees and current planning are highly compatible) based on the definition of the brownfield landscape value and the likely effects of the activity. An assigned score of \(0\) would indicate no apparent or obvious relationship between the brownfield landscape value and the interviewee. Each of the value relationship scores represents a subjective judgment on the part of the rater. The compatibility coefficients of six landscape values are shown in Table 4.  
The degree of value compatibility reflects the comprehensive compatibility relationship between the six landscape values perceived by stakeholders and the renovation and renewal scheme, thus helping to judge the attitude of stakeholders in Jigang toward the renovation and renewal scheme and its spatial change characteristics. As shown in Figure 5, the degree of compatibility is divided into \(10\) grades from \(-1.5\) to \(10\), forming obvious spatial differentiation characteristics in the whole study area, first by forming a positive compatibility distribution center. The degree of compatibility of the \(3200\) m\({}^{3}\) blast furnace and the south gate area is greater than \(5.00\). This area is mainly protected land and green space, and historical value, artistic value, social value, leisure value and cultural value are concentrated in this area, forming a high-value center. Secondly, the distribution center for the negative degree of compatibility is formed. In the site area, the compatibility of several stacking areas, stockyards, gas processing, storage and chemical plants where coal mines, iron ore and other related raw materials were stacked is negative (\(-1.5\)-\(-0.4\)), showing incompatibility and forming a center. Because this area is the core area of industrial production in Jigang and its pollution degree is high, the landscape value of this area is negatively compatible with renovation and renewal. Thirdly, the positive low-value degree of compatibility region is formed. On the periphery of the two positive compatibility centers, a positive low-value degree of compatibility region (\(0.5\)-\(2.4\)) is formed.
